O Wretched Man

Kevin Schaffer

O wretched man ,that I am
Who'll deliver me, from this body of death?
O wretched man, that I am
Who'll deliver me, from this body of death?

I thank God, I thank God
Through Jesus Christ, our Lord
I thank God, I thank God
Through Jesus Christ, our Lord

For the wages of sin, is death
But the gift of God, is eternal life
For the wages of sin, is death
But the gift of God, is eternal life

I thank God, I thank God (I thank the Lord, I thank the Lord)
Through Jesus Christ, our Lord (Through His Son, through His Son)

I praise God, I praise God (I praise the Lord, I praise the Lord)
For Jesus Christ, our Lord (For his Son, for His Son)

Twenty seven fold Amen
