Question concerning resurrection:“If People believe they go directly to heaven when they die! What’s the point of the resurrection?”
The resurrection of the righteous in Jesus Christ will provide the faithful who die in Christ a body fashioned after the body of our Lord (Philippians 3:21) as we will live with Him in the New Jerusalem, a physical kingdom (Revelation 21), and we will see Him just as He is (1 John 3:2). There is an intermediary phase where we will exist in spiritual form in the Spiritual Realm immediately upon our last exhalation in this body of decaying flesh (2 Corinthians 5:8).
At our last exhalation, our spirit, that is essentially the totality of who we intrinsically are, will simply transition “home” into the Spiritual Realm that consumes us, surrounds us, and is only separated by our body of flesh. The Spiritual Realm is NOT some ethereal plane in the distant yonder, but the Spiritual Realm is at our fingertips though we can’t physically apprehend or “grasp” it in its fullness while constrained by flesh and Time and physics.
We are essentially a spirit created in the spiritual image of our God (Genesis 1:26-28) who is Spirit (John 4:24) and though we could exist with our Lord in spiritual form forever, God’s Plan declares a New Heaven and New Earth (Revelation 21), both being physical and interactive via the resurrected body and in a unique turn of events, we will serve our God, Jesus Christ, in resurrected bodies as He will dwell among us in His resurrected body as He is the “first-fruits” of those who have died in faith (1 Corinthians 15:20). Jesus told us that He was going to prepare a place for us and that He would come again and receive us unto Himself that where He is, there we will be also…in our resurrected bodies (John 14:3; Philippians 3:21).
Resurrection of the damned…
There will also be a resurrection of the damned (John 5:28) where those who die having rejected Messiah for the mediation of their sin; these will be resurrected out of Hades-Sheol/Torments (Luke 16; Revelation 20:11-15) and given a body of corruption to stand before our Lord in Judgment (Romans 14:11) and they will lose both body and soul in Hell, forever, in the “second death” (Revelation 20:11-15; Matthew 10:28). The “second death” for mankind is necessary as our Holy God will NOT permit destructive, unrepentant, unatoned for, sin to enter His Kingdom subsequent to the death of the body in Time (Revelation 21:27); after all, it is the destructiveness of sin introduced into the Kingdom before the beginning of Time that initiated the creation of Time, matter and this Earth as a repository for that evil and our Lord’s dealing with same partially within the constraints of Time and physics (Genesis 3:15; 2 Timothy 1:9-10; 1 John 3:8b).
