The Heidelberg Catechism

What is thy only comfort in life and death?

That I with body and soul, both in life and death, [5] am not my own, [6] but belong unto my faithful Saviour Jesus Christ; [7] who, with his precious blood, has fully satisfied for all my sins, [8] and delivered me from all the power of the devil; [9] and so preserves me [10] that without the will of my heavenly Father, not a hair can fall from my head; [11] yea, that all things must be subservient to my salvation, [12] and therefore, by his Holy Spirit, He also assures me of eternal life, [13] and makes me sincerely willing and ready, henceforth, to live unto him.
