"And working together _with Him_ we intreat also that ye receive not the grace of God in vain (for He saith,
At an acceptable time I hearkened unto thee, And in a day of salvation did I succour thee:
behold, now is the acceptable time; behold, now is the day of salvation): giving no occasion of stumbling in anything, that our ministration be not blamed; but in everything commending ourselves, as ministers of God, in much patience, in afflictions, in necessities, in distresses, in stripes, in imprisonments, in tumults, in labours, in watchings, in fastings; in pureness, in knowledge, in long-suffering, in kindness, in the Holy Ghost, in love unfeigned, in the word of truth, in the power of God; by the armour of righteousness on the right hand and on the left, by glory and dishonour, by evil report and good report; as deceivers, and _yet_ true; as unknown, and yet well known; as dying, and behold, we live; as chastened, and not killed; as sorrowful, yet alway rejoicing; as poor, yet making many rich; as having nothing, and _yet_ possessing all things.
"Our mouth is open unto you, O Corinthians, our heart is enlarged. Ye are not straitened in us, but ye are straitened in your own affections. Now for a recompense in like kind (I speak as unto _my_ children), be ye also enlarged."--2 COR. vi. 1-13 (R.V.).
The ministry of the Gospel is a ministry of reconciliation; the preacher of the Gospel is primarily an evangelist. He has to proclaim that wonderful grace of God which made peace between heaven and earth through the blood of the Cross, and he has to urge men to receive it. Until this is done, there is nothing else that he can do. But when sinful men have welcomed the glad tidings, when they have consented to accept the peace bought for them with so great a price, when they have endured to be forgiven and restored to God's favour, not for what they are, nor for what they are going to be, but solely for what Christ did for them on the cross, then a new situation is created, and the minister of the Gospel has a new task. It is to that situation St. Paul addresses himself here. Recognising the Corinthians as people reconciled to God by the death of His Son, he entreats them not to receive the grace of God in vain. He does so, according to our Bibles, as a fellow-worker with God. This is probably right, though some would take the word as in chap. i. 24, and make it mean "as fellow-workers with you." But it is more natural, when we look to what precedes, to think that St. Paul is here identifying himself with God's interest in the world, and that he speaks out of the proud consciousness of doing so. "All is of God," in the great work of redemption; but God does not disdain the sympathetic co-operation of men whose hearts He has touched.
But what is meant by receiving the grace of God in vain, or to no purpose? That might be done in an infinite variety of ways, and in reading the words for edification we naturally grasp at any clue suggested by our circumstances. An expositor is bound to seek his clue rather in the circumstances of the Corinthians; and if we have regard to the general tenor of this Epistle, and especially to such a passage as chap. xi. 4, we shall find the true interpretation without difficulty. Paul has explained his Gospel--his proclamation of Jesus as Universal Redeemer in virtue of His dying the sinner's death, and as Universal Lord in virtue of His resurrection from the dead--so explicitly, because he fears lest through the influence of some false teacher the minds of the Corinthians should be corrupted from the simplicity that is toward Christ. It would be receiving the grace of God in vain, if, after receiving those truths concerning Christ which he had taught them, they were to give up his Gospel for another in which these truths had no place. This is what he dreads and deprecates, both in Corinth and Galatia: the precipitate removal from the grace of Christ to another Gospel which is no Gospel at all, but a subversion of the truth. This is what he means by receiving the grace of God in vain.
