9 If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness. 1 John 1:9
Repentance is an essential part of our relationship with God. It is not enough to simply believe in God, but when Jesus called anyone He called them to follow Him and repent. We know that God is faithful and just to forgive us if we confess our sins. God desires to pour His mercy and grace upon us. He knocks on the hearts of people and those who respond to the drawing of the Holy Spirit are saved and redeemed.
But it is not by accident that we have come into a relationship with Jesus Christ. We were chosen before the foundations of the earth. The Lord has a specific plan and purpose for our lives. No matter where we have come from we can know that if we have confessed our sins to the Lord that He is faithful and just to forgive us.
