“Christians stand on the very brink of eternity. Jesus Christ, the last Adam, has completed the work of the first Adam and entered the new creation. Because Christ did this for us, we now belong to him and share in the rights and privileges of the world-to-come. We have been ‘justified by his grace as a gift’ (Rom. 3:24)
and made ‘fellow heirs with Christ’ so that ‘we may also be glorified with him’ (Rom. 8:17).
We have been ‘raised with Christ’ (Col. 3:1)
and thus our ‘life is hidden with Christ in God’ (Col. 3:3)
and our ‘citizenship is in heaven’ (Phil. 3:20).
Because Jesus has ‘passed through the heavens,’ we today may ‘with confidence draw near to the throne of grace’ (Heb. 4:14, 16),
having ‘confidence to enter the holy places’ (Heb. 10:19).
We eagerly await Christ’s return from heaven when he will ‘transform our lowly body to be like his glorious body’ (Phil. 3:21)
and we will see ‘a new heaven from God … ’ (Rev. 21:1–2).
In light of these things, God has called us ‘to wait for his Son from heaven …’ (1 Thess. 1:10).”
