John Calvin Commentary Colossians 3:4

"When Christ, [who is] our life, shall be manifested, then shall ye also with him be manifested in glory." — Colossians 3:4 (ASV)

But when Christ, our life, shall appear. Here we have an excellent consolation—that the coming of Christ will be the manifestation of our life. And, at the same time, he admonishes us how unreasonable the disposition of anyone would be who refuses to persevere until that day. For if our life is hidden in Christ, it must be hid, until he shall appear.
