It's a turning away from sin and toward the Lord.
Salvation begins with repentance.
It involves a change of mind about sin, which leads to belief in Jesus Christ and brings us the forgiveness of God. It's an ongoing mindset toward sin. Here's the point. Even though we are secure in Christ, we must continue to see sin through God's eyes and acknowledge it as evil. And when we sin, let's repent, confess our wrongdoing, and receive the forgiveness of God.
