We are all called to come to God in repentance and to put our faith in Christ, for we are all sinners saved by God's grace. To say we are not sinners, we would be lying to ourselves and calling God a liar (1 John 1:8-10). We all are like sheep, each one of us going our own way (Isaiah 53:6). We all fall short of the glory of God (Romans 3:23).
God, in His infinite mercy and love, knows that we are mere dust (Psalm 103:14), less than human breath. He has provided a way for mankind to be saved from their sinful nature inherited from Adam and Eve when they disobeyed God in the Garden of Eden (Genesis 3).
God so loved the world that He sent His Son to die for the sins of the world so that we can have eternal life and be restored to a right relationship with Him (John 3:16).
Jesus Christ, His Son, was delivered to the cross for our sins and transgressions and raised alive for our justification (Romans 4:25) so that in God's eyes we are justified by Him who is just and justifies all who come to Him in repentance and put their trust in Him (Romans 3:26).
Jesus is the Son of God, and we are called to put our faith in Him as our Lord and Shepherd, in whom we lack for nothing (Psalm 23:1). He was bruised for our transgressions and pierced for our iniquities; the punishment that was laid on Him brings us peace, and by His wounds, we are healed (Isaiah 53:5).
Christ is the perfect atoning sacrifice for mankind's sinfulness and disobedience of God's fair and just commands (1 John 2:2). As sinners saved by grace, we are called to confess our sins. When we sin, God is faithful and just and will forgive us our sins and purify us from all unrighteousness (1 John 1:9).
So let the wicked man repent of his wicked ways and the unrighteous man forsake his unrighteous thoughts. Let them put their faith in Jesus, and all their past, present, and future sins will be forgiven (Isaiah 55:7). As it is written, we overcome the evil one by the blood of the Lamb and the word of our testimony (Revelation 12:11).
