AN ENTREATY TO LIVE AS CHRISTIANS.
1. This lesson is an admonition to the Corinthians calculated to stimulate them in the performance of the duties they already recognize. The words are easily enough said, but execution is difficult and practice rare. For Paul gives a strange description of the Christian life, and the color and characteristics with which he exhibits it render it decidedly unprepossessing. First he says:
"And working together with him we entreat also that ye receive not the grace of God in vain."
2. He calls the Corinthians co-workers, as in First Corinthians 3, 9, where he puts it: "We are God's fellow-workers; ye are God's husbandry, God's building." That is, we labor upon you with the external Word—teaching and admonishing; but God, working inwardly through the Spirit, gives the blessing and the success. He permits not our labor with the outward Word to be in vain. Therefore, God is the true Master, performing inwardly the supreme work, while we aid outwardly, serving him through the ministry.
The apostle's purpose in praising his co-laborers is to prevent them from despising the external Word as something inessential to them, or well enough known. For though God is able to effect everything without the instrumentality of the outward Word, working inwardly by his Spirit, this is by no means his purpose. He uses preachers as fellow-workers, or co-laborers, to accomplish his purpose through the Word when and where he pleases. Now, since preachers have the office, name and honor of fellow-workers with God, no one may be considered learned enough or holy enough to ignore or despise the most inferior preaching; especially since he knows not when the hour may come wherein God will, through preachers, perform his work in him.
3. Secondly, Paul shows the danger of neglecting the grace of God. He boldly declares here that the preaching of the Gospel is not an eternal, continuous and permanent mode of instruction, but rather a passing shower, which hastens on. What it strikes, it strikes; what it misses, it misses. It does not return, nor does it stand still. The sun and heat follow and dry it up. Experience shows that in no part of the world has the Gospel remained pure beyond the length of man's memory. Only so long as its pioneers lived did it stand and prosper. When they were gone, the light disappeared; factious spirits and false teachers followed immediately.
Thus Moses announces (Deut 31, 29) that the children of Israel will corrupt themselves after his death; and the book of Judges testifies that so it really came to pass. Each time a judge died in whose days the Word of God obtained sway, the people fell away and became more wicked than before. King Joash did what was right so long as the high priest Jehoiada lived, but after the latter's death this had an end. And following the time of Christ and his apostles, the world was filled with seditious spirits and false teachers. Paul, in fact, declares (Acts 20, 29): "I know that after my departing grievous wolves shall enter in among you, not sparing the flock." So also we now have the pure Gospel. This is a time of grace and salvation and the acceptable day; but should the world continue, this condition, too, will soon pass.
4. To receive the grace of God in vain can be nothing else than to hear the pure word of God which presents and offers his grace, and yet to remain listless and irresponsive, undergoing no change at all. Thus, ungrateful for the Word and unworthy of it, we merit the loss of the Word. Such as these are described in the parable (Lk 14, 16-24) where the guests bidden to the supper refused to come and went about their own business, thus provoking the master's anger until he swore they should not taste his supper.
Similar is Paul's threat here, that we may take heed and accept the Gospel with fear and gratitude. Christ says (Jn 12, 35), "Walk while ye have the light, that darkness overtake you not." I should think we might have learned wisdom from experience—from the darkness we suffered under the Papacy. But that is all forgotten; we show neither gratitude nor amendment of life. Very well, we shall find out the consequences.
