"Rejoice in the Lord always: again I will say, rejoice." (Philippians 4:4) "Restore to me the joy of your salvation and grant me a willing spirit to sustain me." (Psalm 51:12) Have you ever felt like you are just wasting away, like your strength is sapped? The normal Christian life is a life of joy. Yet many (if not most) Christians are not consistently joyful. What is it that keeps us from obeying the command to rejoice always? Often, it is unconfessed and unrepented sin that hinders us from living a life of joy. In this short booklet, Jim Wilson shares the story of his early Christian walk and his journey towards understanding the connection between repentance and rejoicing in the Lord. With Scripture, graphs, and clear explanations, he helps us see how failure to confess sins quickly steals our joy and how keeping short accounts—both with God and with others—sets us free to rejoice in the Lord no matter the circumstances.
