The Gospel is good tidings of great joy; the kingdom of God is not in things external, but in joy in the Holy Ghost; and, above all, respect is had to a rejoicing in Christ Jesus, in his person, righteousness, and salvation: and which is consistent with 'trembling' not with a fearful looking for of judgment, but with modesty and humility; in which sense this word, when joined with 'fear' as here, is used Phil 2:12, and stands opposed to pride, haughtiness, and arrogance; men should so rejoice in Christ as to have no confidence in the flesh, or assume any degree of glory to themselves, or have any rejoicing in themselves, but wholly in Christ, giving all the glory of what they have to him.
