The Suffering of Christ for the Forgivess of Sin
Then He said to them, "Thus it is written, and thus it was necessary for the Christ to suffer and to rise from the dead the third day, and that repentance and remission of sins should be preached in His name to all nations, beginning at Jerusalem.
All ought to be told the necessity of repentance. All are by nature desperately wicked. Without repentance and conversion, none can enter the kingdom of God. All ought to be told God's readiness to forgive every one who believes on Christ. All are by nature guilty and condemned. But any one may obtain by faith in Jesus, free, full, and immediate pardon.—All, not least, ought to be continually reminded, that repentance and remission of sins are inseparably linked together. Not that our repentance can purchase our pardon. Pardon is the free gift of God to the believer in Christ. But still it remains true, that a man impenitent is a man unforgiven.
