But know that the LORD has set apart the godly for Himself; the LORD hears when I call to Him.
God made His Christ wonderful in a number of ways. First, He made Him do miracles and thus repudiated the Jews who denied that this man was from the Lord. Second, His manner of life was opposed to the whole world, namely, that He would flee what the whole world sought above all and would seek what the world fled above all. Thus in the first place "He made foolish the wisdom of the world" (1 Corinthians 1:20) by being Himself made foolish to the world; then "He chose what is weak" (that is, sufferings and punishments) "to shame the strong" (that is, agreeable and peaceful things); hence "what is despised and things that are not" (1 Corinthians 1:27f.), such as poverty, contempt, the cross, death, and in general every opinion and "wisdom of the flesh" (Romans 8:6) and of the world. . . . Third, He made Him wonderful in a superexcellent way in that He who alone is wonderful and the author of wonders made Him to be God. This is a great miracle, that the same person is God and man, dead and alive, mortal and immortal, and almost every contradiction is here resolved in Christ.
From First Lectures on the Psalms, on Psalm 4, where the comments follow the Latin translation, which reads: "The Lord hath made His holy one wonderful." (Luther's Works 10:61)
