131 This is the third time I am coming to you. At the mouth of two witnesses or three shall every word established. 2 I have said beforehand, and I do say beforehand, as when I was present the second time, so now, being absent, to them that have sinned heretofore, and to all the rest, that, if I come again, I will not spare; 3 seeing that ye seek a proof of Christ that speaketh in me; who to you-ward is not weak, but is powerful in you: 4 for he was crucified through weakness, yet he liveth through the power of God. For we also are weak in him, but we shall live with him through the power of God toward you.
Matthew Henry's Commentary on 2 Corinthians 13:1-4
Commentary on 2 Corinthians 13:1-6
(Read 2 Corinthians 13:1-6)
Though it is God's gracious method to bear long with sinners, yet he will not bear always; at length he will come, and will not spare those who remain obstinate and impenitent. Christ at his crucifixion, appeared as only a weak and helpless man, but his resurrection and life showed his Divine power. So the apostles, how mean and contemptible soever they appeared to the world, yet, as instruments, they manifested the power of God. Let them prove their tempers, conduct, and experience, as gold is assayed or proved by the touchstone. If they could prove themselves not to be reprobates, not to be rejected of Christ, he trusted they would know that he was not a reprobate, not disowned by Christ. They ought to know if Christ Jesus was in them, by the influences, graces, and indwelling of his Spirit, by his kingdom set up in their hearts. Let us question our own souls; either we are true Christians, or we are deceivers. Unless Christ be in us by his Spirit, and power of his love, our faith is dead, and we are yet disapproved by our Judge.
