Below are John Newton's original lyrics. You will notice that the fourth verse in common usage is not listed. "When we've been there 10,000 years..." was not written by John Newton but was added later! It is attributed to John P. Rees and was first used by Harriet Beecher Stowe, in her novel “Uncle Tom's Cabin”.
Amazing Grace (How sweet the sound) That sav'd a wretch like me! I once was lost, but now am found, Was blind, but now I see.
'Twas grace that taught my heart to fear, And grace my fears reliev'd; How precious did that grace appear, The hour I first believ'd!
Thro' many dangers, toils and snare, I have already come; 'Tis grace has brought me safe thus far, And grace will lead me home.
The Lord has promised good to me. His word my hope secures; He will my shield and portion be, As long as life endures.
Yes, when this flesh and heart shall fail, And mortal life shall cease; I shall profess, within the vail, A life of joy and peace.
The earth shall soon dissolve like snow, The sun forbear to shine; But God, who call'd me here below, Will be for ever mine.
