Trying to change our clothes rather than our hearts and fallen ways is not the path to maturity. In this way each person must take responsibility for his own maturity. God will do His work but we must co-operate by changing. Therefore, we cannot separate repentance from obedience. If repentance was just saying you are sorry then changing would be optional.
Bible repentance means change.
If we have not been birthed into a life of repentance the chances are we will not change very much. Praying for God to lower His standards for the Kingdom so it can include you is an exercise in futility. If we change a little each day we will gradually come up to the Kingdom standards. Any day without change is a wasted day. Our fallen ways are not God's ways.
