Grace by which I stand

This is a Keith Green classic. I've been thinking about my own growth in the Lord through the years. I wonder how I would have fallen if not for the grace of God!

Lord, the feelings are not the same,
I guess I'm older, I guess I've changed.
And how I wish it had been explained,
that as you're growing you must remember,
That nothing lasts, except the grace of God, by which I stand, in Jesus.
I know that I would surely fall away, except for grace, by which I'm saved.

Lord, I remember that special way,
I vowed to serve you, when it was brand new.
But like Peter, I can't even watch and pray, one hour with you,
And I bet, I could deny you too.
But nothing lasts, except the grace of God, by which I stand, in Jesus.
I'm sure that my whole life would waste away,
except for grace, by which I'm saved.
