And they said, Believe on the Lord Jesus Christ, and thou shalt be saved, and thy house. – Acts 16:31

The readiness of God to pardon is to be seen in the fact that He makes no hard conditions with sinners. He does not say, “I will pardon if you suffer this or endure that penance; I will pardon if you perform this act of heroism or that deed of consecration.” No, He himself says, “Believe in the Lord Jesus Christ and thou shalt be saved.” Receive what is freely given-that is the gospel precept, and nothing else. Only confess thy transgressions, or, in other words, own thine emptiness, and then trust thy Savior, and thou art saved.

That He is ready to forgive appears in this yet more glorious fact, that what God demands of man by the gospel He also works in him by His spirit; as for confession of sin He puts the words into the sinner’s mouth, repentance He works in the sinner’s heart, and saving faith His own Spirit creates in the sinner’s soul. Is He not ready to forgive when even what might be called the condition of pardon in one light is under another aspect a gift of free grace?

The sinner’s plea on his lip is, “for Jesus’ sake,” the sinner’s hope in his heart is “for Christ’s sake,”-and it is this that the Father looks at; when He sees that the poor trembling soul has embraced Jesus, His own dear Son, the Father puts the sin away at once without a word, and says, “Be of good cheer, thy sins are forgiven thee, go in peace.” ~ C.H.
