If then you were raised with Christ, seek those things which are above, where Christ is, sitting at the right hand of God.
~ Colossians 3:1 (NKJV)
Ascension follows resurrection: hence, if we are the members of Christ we must ascend into heaven, because he, on being raised up from the dead, was received up into heaven, that he might draw us up with him. Now, we seek those things which are above, when in our minds we are truly sojourners in this world, and are not bound to it… Let us therefore bear in mind that that is a true and holy thinking as to Christ, which forthwith bears us up into heaven, that we may there adore him, and that our minds may dwell with him.
~ John Calvin, Commentary on the Book of Colossians
