The Lord our God is merciful and forgiving,

The Lord our God is merciful and forgiving, even though we have rebelled against him. Daniel 9:9
Are you haunted by past sins? Perhaps Satan, the accuser, keeps reminding you of mistakes you’ve made in your life. If so, rebuke him right now with the truth that you, as a believer in Jesus Christ, have been forgiven.
Don’t listen to the lies of the enemy. Instead, turn to the Word of God and read about Paul, who calls himself the chief of sinners (1 Timothy 1:15). In the book of Acts, a man named Saul was persecuting the church. He gave his consent to the martyrdom of Stephen and traveled around hunting believers of the Way and punishing them. After Saul met Jesus, however, he gave his life completely over to the Lord and became Paul, the apostle who wrote much of the New Testament.
