Isaiah 42:16 KJV — And I will bring the blind by a way that they knew not; I will lead them in paths that they have not known: I will make darkness light before them, and crooked things straight. These things will I do unto them, and not forsake them.
The Old Covenant in the Bible is based on what God will do for you, not on what you will do for God.
The New Covenant that we’re under is even better. It’s based on what God has done for you, and not what you will do for God.
Neither one is based on you or your works.
All you have to do is believe and receive God’s finished work for you.
