God is not a God of sadness, death, etc., but the devil is. Christ is a God of joy, and so the Scriptures often say that we should rejoice ... A Christian should and must be a cheerful person.
Martin LutherAnything that one imagines of God apart from Christ is only useless thinking and vain idolatry.
Martin LutherI simply taught, preached, wrote God's Word: otherwise I did nothing. The Word of God did it all.
Martin LutherBut Satan, the god of all dissension, stirreth up daily new sects, and last of all (which of all other I should never have foreseen or once suspected) he hath raised up a sect of such as teach that the Ten Commandments ought to be taken out of the church, and that men should not be terrified with the law, but gently exerted by the preaching of the grace of Christ.
Martin LutherFeelings come and feelings go, And feelings are deceiving; My warrant is the Word of God-- Naught else is worth believing. Though all my heart should feel condemned For want of some sweet token, There is One greater than my heart Whose Word cannot be broken. I'll trust in God's unchanging Word Till soul and body sever, For, though all things shall pass away, HIS WORD SHALL STAND FOREVER!
Martin Luther
