The voice of John the Baptist was crying out in the wilderness…a message of forgiveness. To understand your need for forgiveness, you must see how sinful you are.
God is willing to forgive, but repentance is a requirement. Repentance is not a work that you do to receive salvation. It is not a work of the flesh. It is a work of the Spirit.
Repentance and faith always go hand-in-hand. They’re inseparable graces. Repent = turn from old sin/Faith = turn to God [1 Thessalonians 1:9; Acts 5:31] It is God who gives repentance. The Spirit works in us to give us. [2 Timothy 2:24-25]
You can be sorry and stop doing certain things, but it is fleeting if it is in the flesh. But with godly sorrow, our hearts our turned towards God and you don’t want to sin. You have a zeal for the glory of God and a zeal to hate the things He hates. [2 Corinthians 7:9-11]
