The biblical way to express God’s love to a sinner is to show him how great his sin is (using the Law—see Romans 7:13; Galatians 3:24), and then give him the incredible grace of God in Christ.
The Gospel comes in power and the Holy Spirit, with much assurance. If you call upon the name of the Lord, God will transform you on the inside, give you the shock of your life, and give you everlasting life on top of that.
When men don't fear god, they give themselves to evil
