2:17 For we are not as many, which {l} corrupt the word of God: but as of sincerity, but as of God, in the sight of God speak we in Christ.
(l) We do not handle it craftily and covetously, or less sincerely than we ought. And he uses a metaphor, which is taken from hucksters, who used to play the false harlot with whatever came into their hands.
2:17 We are not as many, who corrupt the word of God. The Greek city figure is taken from the tavern-keepers who adulterate the wine they offer for sale. There were those at Corinth, Judaizing teachers, who adulterated the gospel with ingredients of Judaism. These are the false brethren (2Co 11:26) with whom his whole ministry was a struggle. See also Ga 2:4.
But as of sincerity, but as of God. On the contrary, he and his fellow-preachers spoke the words of genuine sincerity and with a sense of responsibility to God.
2:17 For we are not as many, who adulterate the word of God - Like those vintners (so the Greek word implies) who mix their wines with baser liquors. But as of sincerity - Without any mixture. But as from God - This rises higher still; transmitting his pure word, not our own. In the sight of God - Whom we regard as always present, and noting every word of our tongue. Speak we - The tongue is ours, but the power is God's. In Christ - Words which he gives, approves, and blesses.
2:12-17 A believer's triumphs are all in Christ. To him be the praise and glory of all, while the success of the gospel is a good reason for a Christian's joy and rejoicing. In ancient triumphs, abundance of perfumes and sweet odours were used; so the name and salvation of Jesus, as ointment poured out, was a sweet savour diffused in every place. Unto some, the gospel is a savour of death unto death. They reject it to their ruin. Unto others, the gospel is a savour of life unto life: as it quickened them at first when they were dead in trespasses and sins, so it makes them more lively, and will end in eternal life. Observe the awful impressions this matter made upon the apostle, and should also make upon us. The work is great, and of ourselves we have no strength at all; all our sufficiency is of God. But what we do in religion, unless it is done in sincerity, as in the sight of God, is not of God, does not come from him, and will not reach to him. May we carefully watch ourselves in this matter; and seek the testimony of our consciences, under the teaching of the Holy Spirit, that as of sincerity, so speak we in Christ and of Christ.
