John Newton lived 82 years and preached and had an active ministry until beset by fading health in the last two years of his life. Even then, Newton never ceased to be amazed by God’s grace and told his friends:
My memory is nearly gone;
but I remember two… things;
That I am a great sinner, and that Christ is a great Saviour.
