WCF 15.1, Repentance unto Life Is a Gospel Gift that Must Be Preached

Mourning over sin is a gift of gospel grace that comes in/with/from Christ and His redemption. The way repentance unto life comes is by the Spirit, using words. And this is for the nations, not just for Israel. The entire Bible teaches repentance unto life, which all preachers must preach, and which the promised Spirit attends with almighty power. Repentance and remission (forgiveness) is the message of their mission. Jesus's preaching of the gospel of the kingdom is summarized, "repent, and believe." Preachers who do not preach repentance are holding back God's saving Word and guilty of the blood of their hearers.
