We read in our Gospel that “Jesus was led up of the Spirit into the wilderness,” that is, the Holy Ghost brought Him thither. … That Christ did not go into the wilderness of His own accord, but was led up by the Spirit, is a fact of the greatest importance and should be well remembered. We should imitate this example, and never do anything through an impulse of our own feelings; but what we do must ever be done in obedience to the Word and command of God. Let us always first ascertain whether God orders us to do a thing, and when we are assured of this, then let us diligently do it, and do nothing without His Word.
The general duties and works of love need no new command; they are already laid down and ordered in the Ten Commandments. We are all enjoined of God to hear His Word, to love Him, to pray to Him, to be obedient to our parents, to love our neighbor, to shun all lasciviousness and to hold matrimony in high esteem. All this is God’s will and institution; therefore no especial call of the Holy Spirit to enter matrimony, to become father or mother, is needed. Such matters have all been arranged and commanded of God. (Luther’s House Postil, Sermon for Invocavit, Volume 1, p. 257-258)
