(1) The offer of salvation in the way of faith and repentance does not pretend to be a revelation of the secret counsel of God, more specifically, of His design in giving Christ as an atonement for sin. It is simply the promise of salvation to all those who accept Christ by faith.
(2) This offer, in so far as it is universal, is always conditioned by faith and conversion. Moreover, it is contingent on a faith and repentance such as can only be wrought in the heart of man by the operation of the Holy Spirit.
(3) The universal offer of salvation does not consist in the declaration that Christ made atonement for every man that hears the gospel, and that God really intends to save each one. It consists in (a) an exposition of the atoning work of Christ as in itself sufficient for the redemption of all men; (b) a description of the real nature of the repentance and faith that are required incoming to Christ; and (c) a declaration that each one who comes to Christ with true repentance and faith will obtain the blessings of salvation.
(4) it is not the duty of the preacher to harmonize the secret counsel of God respecting the redemption of sinners with His declarative will, as expressed in the universal offer of salvation. He is simply an official ambassador, whose duty it is to carry out the will of the Lord in preaching the gospel to all men indiscriminately.
(5) Dr. Shedd says: "The universal offer of the benefits of Christ's atonement springs out of God's will of complacency, Eze 33:11. God may properly call upon the non-elect to do a thing that God delights in, simply because He does delight in it. The divine desire is not altered by the divine decree of preterition.
(6) The universal offer of salvation serves the purpose of disclosing the aversion and obstinacy of man in his opposition to the gospel, and of removing every vestige of excuse. If it were not made, sinners might say that they would gladly have accepted the gift of God, if it only had been offered to them.
