How did the risen Jesus convince His disciples?

Now after the Sabbath, as it began to dawn on the first day of the week, Mary Magdalene and the other Mary came to see the tomb. Behold, there was a great earthquake, for an angel of the Lord descended from the sky, and came and rolled away the stone from the door, and sat on it. His appearance was like lightning, and his clothing white as snow. For fear of him, the guards shook, and became like dead men. The angel answered the women, “Don’t be afraid, for I know that you seek Jesus, who has been crucified. He is not here, for he has risen, just like he said. Come, see the place where the Lord was lying. Go quickly and tell his disciples, ‘He has risen from the dead, and behold, he goes before you into Galilee; there you will see him.’ Behold, I have told you.” They departed quickly from the tomb with fear and great joy, and ran to bring his disciples word. As they went to tell his disciples, behold, Jesus met them, saying, “Rejoice!” They came and took hold of his feet, and worshiped him.In the end of the sabbath, as it began to dawn toward the first day of the week, came Mary Magdalene and the other Mary to see the sepulchre. And, behold, there was a great earthquake: for the angel of the Lord descended from heaven, and came and rolled back the stone from the door, and sat upon it. His countenance was like lightning, and his raiment white as snow: And for fear of him the keepers did shake, and became as dead men. And the angel answered and said unto the women, Fear not ye: for I know that ye seek Jesus, which was crucified. He is not here: for he is risen, as he said. Come, see the place where the Lord lay. And go quickly, and tell his disciples that he is risen from the dead; and, behold, he goeth before you into Galilee; there shall ye see him: lo, I have told you. And they departed quickly from the sepulchre with fear and great joy; and did run to bring his disciples word. And as they went to tell his disciples, behold, Jesus met them, saying, All hail. And they came and held him by the feet, and worshipped him.

When therefore it was evening, on that day, the first day of the week, and when the doors were locked where the disciples were assembled, for fear of the Jews, Jesus came and stood in the midst, and said to them, “Peace be to you.” When he had said this, he showed them his hands and his side. The disciples therefore were glad when they saw the Lord. Jesus therefore said to them again, “Peace be to you. As the Father has sent me, even so I send you.” When he had said this, he breathed on them, and said to them, “Receive the Holy Spirit! If you forgive anyone’s sins, they have been forgiven them. If you retain anyone’s sins, they have been retained.”Then the same day at evening, being the first day of the week, when the doors were shut where the disciples were assembled for fear of the Jews, came Jesus and stood in the midst, and saith unto them, Peace be unto you. And when he had so said, he shewed unto them his hands and his side. Then were the disciples glad, when they saw the Lord. Then said Jesus to them again, Peace be unto you: as my Father hath sent me, even so send I you. And when he had said this, he breathed on them, and saith unto them, Receive ye the Holy Ghost: Whose soever sins ye remit, they are remitted unto them; and whose soever sins ye retain, they are retained.

But Thomas, one of the twelve, called Didymus, wasn’t with them when Jesus came. The other disciples therefore said to him, “We have seen the Lord!” But he said to them, “Unless I see in his hands the print of the nails, and put my hand into his side, I will not believe.” After eight days again his disciples were inside, and Thomas was with them. Jesus came, the doors being locked, and stood in the midst, and said, “Peace be to you.” Then he said to Thomas, “Reach here your finger, and see my hands. Reach here your hand, and put it into my side. Don’t be unbelieving, but believing.” Thomas answered him, “My Lord and my God!” Jesus said to him, “Because you have seen me,you have believed. Blessed are those who have not seen, and have believed.”But Thomas, one of the twelve, called Didymus, was not with them when Jesus came. The other disciples therefore said unto him, We have seen the Lord. But he said unto them, Except I shall see in his hands the print of the nails, and put my finger into the print of the nails, and thrust my hand into his side, I will not believe. And after eight days again his disciples were within, and Thomas with them: then came Jesus, the doors being shut, and stood in the midst, and said, Peace be unto you. Then saith he to Thomas, Reach hither thy finger, and behold my hands; and reach hither thy hand, and thrust it into my side: and be not faithless, but believing. And Thomas answered and said unto him, My Lord and my God. Jesus saith unto him, Thomas, because thou hast seen me, thou hast believed: blessed are they that have not seen, and yet have believed.

Behold, two of them were going that very day to a village named Emmaus, which was sixty stadia from Jerusalem. They talked with each other about all of these things which had happened. While they talked and questioned together, Jesus himself came near, and went with them. But their eyes were kept from recognizing him. He said to them, “What are you talking about as you walk, and are sad?” One of them, named Cleopas, answered him, “Are you the only stranger in Jerusalem who doesn’t know the things which have happened there in these days?” He said to them, “What things?” They said to him, “The things concerning Jesus, the Nazarene, who was a prophet mighty in deed and word before God and all the people; and how the chief priests and our rulers delivered him up to be condemned to death, and crucified him. But we were hoping that it was he who would redeem Israel. Yes, and besides all this, it is now the third day since these things happened. Also, certain women of our company amazed us, having arrived early at the tomb; and when they didn’t find his body, they came saying that they had also seen a vision of angels, who said that he was alive. Some of us went to the tomb, and found it just like the women had said, but they didn’t see him.” He said to them, “Foolish men, and slow of heart to believe in all that the prophets have spoken! Didn’t the Christ have to suffer these things and to enter into his glory?” Beginning from Moses and from all the prophets, he explained to them in all the Scriptures the things concerning himself. They drew near to the village, where they were going, and he acted like he would go further. They urged him, saying, “Stay with us, for it is almost evening, and the day is almost over.” He went in to stay with them. When he had sat down at the table with them, he took the bread and gave thanks. Breaking it, he gave to them. Their eyes were opened, and they recognized him, and he vanished out of their sight. They said one to another, “Weren’t our hearts burning within us, while he spoke to us along the way, and while he opened the Scriptures to us?” They rose up that very hour, returned to Jerusalem, and found the eleven gathered together, and those who were with them, saying, “The Lord is risen indeed, and has appeared to Simon!” They related the things that happened along the way, and how he was recognized by them in the breaking of the bread.And, behold, two of them went that same day to a village called Emmaus, which was from Jerusalem about threescore furlongs. And they talked together of all these things which had happened. And it came to pass, that, while they communed together and reasoned, Jesus himself drew near, and went with them. But their eyes were holden that they should not know him. And he said unto them, What manner of communications are these that ye have one to another, as ye walk, and are sad? And the one of them, whose name was Cleopas, answering said unto him, Art thou only a stranger in Jerusalem, and hast not known the things which are come to pass there in these days? And he said unto them, What things? And they said unto him, Concerning Jesus of Nazareth, which was a prophet mighty in deed and word before God and all the people: And how the chief priests and our rulers delivered him to be condemned to death, and have crucified him. But we trusted that it had been he which should have redeemed Israel: and beside all this, to day is the third day since these things were done. Yea, and certain women also of our company made us astonished, which were early at the sepulchre; And when they found not his body, they came, saying, that they had also seen a vision of angels, which said that he was alive. And certain of them which were with us went to the sepulchre, and found it even so as the women had said: but him they saw not. Then he said unto them, O fools, and slow of heart to believe all that the prophets have spoken: Ought not Christ to have suffered these things, and to enter into his glory? And beginning at Moses and all the prophets, he expounded unto them in all the scriptures the things concerning himself. And they drew nigh unto the village, whither they went: and he made as though he would have gone further. But they constrained him, saying, Abide with us: for it is toward evening, and the day is far spent. And he went in to tarry with them. And it came to pass, as he sat at meat with them, he took bread, and blessed it, and brake, and gave to them. And their eyes were opened, and they knew him; and he vanished out of their sight. And they said one to another, Did not our heart burn within us, while he talked with us by the way, and while he opened to us the scriptures? And they rose up the same hour, and returned to Jerusalem, and found the eleven gathered together, and them that were with them, Saying, The Lord is risen indeed, and hath appeared to Simon. And they told what things were done in the way, and how he was known of them in breaking of bread.

Jesus came to them and spoke to them, saying, “All authority has been given to me in heaven and on earth. Go,and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all things that I commanded you. Behold, I am with you always, even to the end of the age.” Amen.And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth. Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen.

But you will receive power when the Holy Spirit has come upon you. You will be witnesses to me in Jerusalem, in all Judea and Samaria, and to the uttermost parts of the earth.” When he had said these things, as they were looking, he was taken up, and a cloud received him out of their sight.But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judea, and in Samaria, and unto the uttermost part of the earth. And when he had spoken these things, while they beheld, he was taken up; and a cloud received him out of their sight.

If Christ has not been raised, then our preaching is in vain, and your faith also is in vain.And if Christ be not risen, then is our preaching vain, and your faith is also vain.

If Christ has not been raised, your faith is vain; you are still in your sins. Then they also who are fallen asleep in Christ have perished. If we have only hoped in Christ in this life, we are of all men most pitiable. But now Christ has been raised from the dead. He became the first fruits of those who are asleep.And if Christ be not raised, your faith is vain; ye are yet in your sins. Then they also which are fallen asleep in Christ are perished. If in this life only we have hope in Christ, we are of all men most miserable. But now is Christ risen from the dead, and become the firstfruits of them that slept.
