What is the difference between assurance and presumption?
Assurance is the confidence the Spirit gives through God's promise and the fruit He produces in a life that trusts Christ. Presumption is confidence with nothing behind it: a claim to belong to Jesus that a look at the life does not support. The difference is not in the strength of the feeling but in its basis: one rests on the testimony of God, the other on a wish.
This question arose from studying Can I lose my salvation? and How do I know the Spirit's witness from my own feelings?.

What the Scripture says
Assurance rests on God's testimony, not on our feelings
John states his purpose plainly: 'These things I have written to you who believe in the name of the Son of God, that you may know that you have eternal life.' The ground is the testimony of God concerning His Son, which the Spirit confirms: 'The Spirit himself testifies with our spirit that we are children of God.' Assurance is not a mood; it is faith leaning on a promise that cannot be broken.
These things I have written to you who believe in the name of the Son of God, that you may know that you have eternal life, and that you may continue to believe in the name of the Son of God.
He who believes in the Son of God has the testimony in himself. He who doesn’t believe God has made him a liar, because he has not believed in the testimony that God has given concerning his Son. The testimony is this, that God gave to us eternal life, and this life is in his Son.
For you didn’t receive the spirit of bondage again to fear, but you received the Spirit of adoption, by whom we cry, “Abba! Father!” The Spirit himself testifies with our spirit that we are children of God;
Presumption claims what it has not been given
Jesus warns of people on the last day who say, 'Lord, Lord, didn't we prophesy in your name... do many mighty works?' and He answers, 'I never knew you. Depart from me, you who work iniquity.' A claim to Christ without the will of the Father is presumption, however confident or impressive it sounds. The Pharisee who thanked God he was not like other men went home unjustified; the tax collector who begged for mercy went home forgiven.
Not everyone who says to me, ‘Lord, Lord,’ will enter into the Kingdom of Heaven; but he who does the will of my Father who is in heaven. Many will tell me in that day, ‘Lord, Lord, didn’t we prophesy in your name, in your name cast out demons, and in your name do many mighty works?’ Then I will tell them, ‘I never knew you. Depart from me, you who work iniquity.’
He spoke also this parable to certain people who were convinced of their own righteousness, and who despised all others. “Two men went up into the temple to pray; one was a Pharisee, and the other was a tax collector. The Pharisee stood and prayed to himself like this: ‘God, I thank you, that I am not like the rest of men, extortionists, unrighteous, adulterers, or even like this tax collector. I fast twice a week. I give tithes of all that I get.’ But the tax collector, standing far away, wouldn’t even lift up his eyes to heaven, but beat his breast, saying, ‘God, be merciful to me, a sinner!’ I tell you, this man went down to his house justified rather than the other; for everyone who exalts himself will be humbled, but he who humbles himself will be exalted.”
Assurance obeys; presumption excuses
John ties knowing to doing: 'This is how we know that we know him: if we keep his commandments,' and 'whoever says, I know him, and doesn't keep his commandments, is a liar.' James adds that faith without works is dead, and Paul names people who 'profess that they know God, but by their works they deny him.' Assurance produces likeness to the one trusted; presumption produces a slogan. You can tell the difference, over time, by the direction of a life.
This is how we know that we know him: if we keep his commandments. One who says, “I know him,” and doesn’t keep his commandments, is a liar, and the truth isn’t in him.
he who says he remains in him ought himself also to walk just like he walked.
Even so faith, if it has no works, is dead in itself.
They profess that they know God, but by their works they deny him, being abominable, disobedient, and unfit for any good work.
Assurance perseveres; presumption is caught unprepared
Peter urges us to make our 'calling and election sure' by adding the virtues to faith, promising that when these are yours and abound 'you will never stumble.' The ten virgins are separated by what they actually brought; the foolish find the door shut and hear, 'I don't know you.' Paul's caution cuts both ways: 'let him who thinks he stands be careful that he doesn't fall.' Assurance lives in the present tense of trust; presumption banks on the past.
Therefore, brothers, be more diligent to make your calling and election sure. For if you do these things, you will never stumble. For thus you will be richly supplied with the entrance into the eternal Kingdom of our Lord and Savior, Jesus Christ.
Yes, and for this very cause adding on your part all diligence, in your faith supply moral excellence; and in moral excellence, knowledge; and in knowledge, self-control; and in self-control patience; and in patience godliness; and in godliness brotherly affection; and in brotherly affection, love. For if these things are yours and abound, they make you to be not idle nor unfruitful to the knowledge of our Lord Jesus Christ.
“Then the Kingdom of Heaven will be like ten virgins, who took their lamps, and went out to meet the bridegroom. Five of them were foolish, and five were wise. Those who were foolish, when they took their lamps, took no oil with them, but the wise took oil in their vessels with their lamps. Now while the bridegroom delayed, they all slumbered and slept. But at midnight there was a cry, ‘Behold! The bridegroom is coming! Come out to meet him!’ Then all those virgins arose, and trimmed their lamps. The foolish said to the wise, ‘Give us some of your oil, for our lamps are going out.’ But the wise answered, saying, ‘What if there isn’t enough for us and you? You go rather to those who sell, and buy for yourselves.’ While they went away to buy, the bridegroom came, and those who were ready went in with him to the marriage feast, and the door was shut. Afterward the other virgins also came, saying, ‘Lord, Lord, open to us.’ But he answered, ‘Most certainly I tell you, I don’t know you.’ Watch therefore, for you don’t know the day nor the hour in which the Son of Man is coming.
Therefore let him who thinks he stands be careful that he doesn’t fall.
The test: believe the promise, examine the fruit
John gives a threefold test: we know He remains in us 'by the Spirit which he gave us,' we know we have passed out of death into life 'because we love the brothers,' and when our heart condemns us, 'God is greater than our heart.' The anchor is the promise: by two unchangeable things, in which it is impossible for God to lie, we have 'strong encouragement' and 'the anchor of the soul.' If your confidence is built on Christ's finished work and is producing love, it is assurance; if it is built on a wish, repentance is the door to the real thing.
He who keeps his commandments remains in him, and he in him. By this we know that he remains in us, by the Spirit which he gave us.
We know that we have passed out of death into life, because we love the brothers. He who doesn’t love his brother remains in death.
And by this we know that we are of the truth, and persuade our hearts before him, because if our heart condemns us, God is greater than our heart, and knows all things.
that by two immutable things, in which it is impossible for God to lie, we may have a strong encouragement, who have fled for refuge to take hold of the hope set before us. This hope we have as an anchor of the soul, a hope both sure and steadfast and entering into that which is within the veil;

Scripture raises the next question
Studying the Word naturally opens more of it. Follow what you just read: it leads somewhere.
We haven't written this one yet. Take it to your church or small group: the Word answers it wherever it is asked. If we study it here later, all the better.

Verses to meditate on
These things I have written to you who believe in the name of the Son of God, that you may know that you have eternal life, and that you may continue to believe in the name of the Son of God.
The Spirit himself testifies with our spirit that we are children of God;
Not everyone who says to me, ‘Lord, Lord,’ will enter into the Kingdom of Heaven; but he who does the will of my Father who is in heaven. Many will tell me in that day, ‘Lord, Lord, didn’t we prophesy in your name, in your name cast out demons, and in your name do many mighty works?’ Then I will tell them, ‘I never knew you. Depart from me, you who work iniquity.’
Therefore, brothers, be more diligent to make your calling and election sure. For if you do these things, you will never stumble.
This is how we know that we know him: if we keep his commandments. One who says, “I know him,” and doesn’t keep his commandments, is a liar, and the truth isn’t in him.
