You are always going to be working on something, so learn to separate your 'who' from your 'do'. Who you are in Christ is a settled issue. 'There is therefore now no condemnation to those who are in Christ Jesus...' (Romans 8:1 NKJV) Because God has chosen to see you 'in Christ', you are always acceptable to Him and you always have access to Him.
Your 'who' is not based on your 'do'. Your 'who' determines your salvation, your 'do' determines your future rewards in Heaven. God is not condemning you, you are condemning yourself! God will convict you, and when you repent of sin He will cleanse you, but He will never condemn you. Satan does that. You do that to yourself. But God never will. 'Who is he who condemns? It is Christ who died, and furthermore is also risen, who is even at the right hand of God, who makes intercession for us.' (Romans 8:34 NKJV) Every time you fail, Christ your advocate offers His atoning blood to cover your sin. As a result, God sees you as 'accepted'.
Stop comparing yourself with somebody else. You are you, and you will never be them. We are all equal in Christ! So when somebody condemns you, stand on this Scripture: 'Surely the Lord God will help me; who is he who will condemn me?
Isaiah 50:9 NKJV
Surely the Lord God will help Me; Who is he who will condemn Me? Indeed they will all grow old like a garment; The moth will eat them up.
