1 Timothy 1:12-17 – 12 I thank Christ Jesus our Lord, who has given me strength, that he considered me faithful, appointing me to his service. 13 Even though I was once a blasphemer and a persecutor and a violent man, I was shown mercy because I acted in ignorance and unbelief. 14 The grace of our Lord was poured out on me abundantly, along with the faith and love that are in Christ Jesus.
15 Here is a trustworthy saying that deserves full acceptance: Christ Jesus came into the world to save sinners —of whom I am the worst. 16 But for that very reason I was shown mercy so that in me, the worst of sinners, Christ Jesus might display his unlimited patience as an example for those who would believe on him and receive eternal life. 17 Now to the King eternal, immortal, invisible, the only God, be honor and glory for ever and ever. Amen.
Don’t let Satan beat you down into making you feel unworthy. Focus on God and strengthen in the Holy Spirit. If Paul allowed Satan to convince him that he couldn’t possibly serve God after his previous acts we would be out one of our most effective missionaries. The Lord is full of mercy and loves you. Run towards Him and allow Him to use you.
