Heidelberg Catechism 18.49

Chapter 18 — Lord's Day 18

Section 49. Q. 49: How does Christ's ascension to heaven benefit us? A. First, he pleads our cause in heaven in the presence of his Father. Second, we have our own flesh in heaven — a guarantee that Christ our head will take us, his members, to himself in heaven. Third, he sends his Spirit to us on earth as a further guarantee. By the Spirit's power we make the goal of our lives, not earthly things, but the things above where Christ is, sitting at God's right hand.
