Lo! my God, without merit on my part, of His pure and free mercy, has given to me (an unworthy, condemned, and contemptible creature) all the riches of justification and salvation in Christ.For such a Father then, who has overwhelmed me with these inestimable riches of His, why should I not freely, cheerfully, with my whole heart and with an eager will, do all that I know will be pleasing to Him, and acceptable in His sight?I will therefore give myself, as a sort of Christ, to my neighbor, as Christ has given Himself to me; and will do nothing in this life, except what I see will be needful, advantageous, and wholesome for my neighbor, since by faith I abound in all good things in Christ.
~ Martin Luther
