Colossians 1:29

Whereunto I also labour,.... In the word and doctrine, by preaching Christ, warning sinners of their danger, teaching them the way of salvation, and their duty; with this view, that, in thee great day of account, he might bring a large number of them, and set them before Christ as the seals of his ministry, as instances of the grace of Christ, and as perfect in him:

striving according to his working, which worketh in me mightily; meaning either in his prayers, earnestly entreating of God that he would succeed his labours, and bless them to the conversion of many; which sense is favoured by the Syriac version, which renders it,

ומתכשף, "and make supplication"; that is, with that effectual fervent prayer, which was powerfully wrought in him: or in his ministry, combating with many enemies, fighting the good fight of faith; not in his own strength, but through the power of Christ; which enabled him to preach the Gospel far and near, in season and out of season; which supported his outward man, and strengthened his inward man for that service, and made it effectual to the good of the souls of many: some refer this to the signs, wonders, and miracles, which Christ wrought by him, for the confirmation of the Gospel; but the other sense, which takes in both the power by which he was assisted in preaching, both in body and soul, and that which went along with his ministry to make it useful to others, is to be preferred.
