I Me My!
It is the regenerate I in its impotence seeking to obey the law without being Filled With the Spirit.
This is the experience of almost every saint.
After Conversion a man begins to do his best, and he fails;
But if we are Brought Into Full Light, we need fail no longer.
Nor need we fail at all if we have Received the Spirt in His Fullness at Conversion.
