If you feel like you can never measure up, that no matter what you do it is never good enough, let me suggest that you may be focusing too much on your daily walk and too little on the finished work of Christ. The key to living an overcoming life is to focus on what Jesus has done for you rather than on what you are doing for Him.
“There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit.”
— Romans 8:1 (KJV)
Father God, help me to trust only in the finished work of Jesus Christ even as I put off my old sinful nature. Help me to put on my new nature, which is created to be like Jesus—truly righteous and holy. In the name of Jesus I pray, amen.
