6. Pardon of sin is according to the riches, fulness, and freeness of the grace of God, (Eph. 1:7) the promise of it in the covenant is free, absolute, and unconditional, (Heb. 8:12) the proclamation of it in the gospel, bore witness to by all the prophets, is the same, (Ex. 34:6; Acts 10:43, 13:38) the blood of Christ was shed freely for it; and though it cost him dear, it is all of free grace to sinners, without money and without price. Christ is exalted as a prince to “give” it; and God, for Christ’s sake, frankly forgives all trespasses, (Acts 5:31; Luke 7:41, 42; Col. 2:13) and it is vouchsafed to the worst and chief of sinners, (1 Tim. 1:13) and to great backsliders, ungrateful persons, guilty of sins of omission and commission, (Hosea 14:4; Isa. 43:22-25).
