1 Thessalonians 4:2
For you know what commandments we gave you by the Lord Jesus.
Christ does not appeal to men as the heathen philosophers did. They ask opinions, court criticism, and even the wily and garrulous Socrates gives men an opportunity of differing from him; but Christ, with "the authoritative tone and earnestness" of the Son of God, says, "This is absolute; believe it and be saved, or reject it and be damned." He says that He came from the Father, that He speaks the Word of the Father, and that He is returning to the Father. So there is nothing between Him and God; immediately behind Him, though invisible, lies infinitude, and He sets Himself up as the medium on which the voice of the infinite is broken into human sounds.
(J. Parker, D. D.)
