John Newton[1] 

“I am not what I ought to be – ah, how imperfect and deficient! I am not what I wish to be – I abhor what is evil, and I would cleave to what is good! I am not what I hope to be – soon, soon shall I put off mortality, and with mortality all sin and imperfection. Yet though I am not what I ought to be, nor what I wish to be, nor what I hope to be, I can truly say, I am not what I once was; a slave to sin and Satan; and I can heartily join with the apostle, and acknowledge, ‘By the grace of God I am what I am.’”
