131 This is the third time that I am coming to you. From the mouth of two or three witnesses will every word be made certain. 2 I said before, and still say it before I come, as being present for the second time, though I am still away from you, to those who have done wrong before, and to all the others, that if I come again I will not have pity; 3 Seeing that you are looking for a sign of Christ giving out his word in me; who is not feeble in relation to you, but is strong in you: 4 For he was feeble in that he was put to death on the cross, but he is living by the power of God. And we are feeble in him, but we will be living with him through the power of God in relation to 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.
