For He saith, I have heard thee in a time accepted, and in the day of salvation have I succoured thee: behold, now is the accepted time; behold, now is the day of salvation. – 2 Corinthians 6:2
Jesus’ sighs, and tears, and bloody sweat in the garden of Gethsemane did not fall unheeded; like the blood of Abel, they cried from the ground, and were heard acceptably above; an answer was given: this was plainly proved by the descent of the angel to strengthen the Savior; so the prophetic words add, “In a time accepted, and in the day of salvation have I succoured thee.” The apostle infers from this, that inasmuch as God hath accepted Christ, the representative of His people, He hath thereby ushered in an era of acceptance. Acceptance given to the Savior is, in the apostle’s view, acceptance given to sinners. Inasmuch as Christ is heard-He prayed not for Himself, but for us-there is therefore an accepted time for us begun and commenced from the day when Christ went up to the tree, stretched His hands to the nails, bowed His head to death, and said, “It is finished.” Paraphrase the text thus: ” I have heard Jesus, the surety, in an acceptable time; in the day of salvation have I succoured Him, the mighty Savior; and therefore, to you, My people, to you, poor lost and wandering sinners, to you, now is the accepted time; now is the day of salvation.” If Christ had not died, there had never been a day of salvation. If Christ had not been heard and accepted, an accepted time there never could have come to us; but since He, man’s representative, hath obtained favor in the eyes of God, and through His complete work, hath for ever settled that favor upon Himself, there is favor in the heart of God to those whom Christ represented, even to those transgressors for whom He maketh intercession. ~ C.H.
