Christ will come back a second time to collect His church. At that time our corrupt bodies (whether dead or alive) will be raised the same way that Jesus was raised on the third day. This is our hope (our expectancy)
Philippians 3:20-21 NKJV
…we also eagerly wait for the Savior, the Lord Jesus Christ, who will transform our lowly body that it may be conformed to His glorious body…
IT’S ALREADY IN US
The power that will raise our bodies to look like Jesus is already in us now. We are already prepared with the resurrection power. The resurrection is simply when all the power that has been in us since we were born again comes out!
2 Corinthians 5:4-5 NKJV
For we who are in this tent groan, being burdened, not because we want to be unclothed, but further clothed, that mortality may be swallowed up by life. Now He who has prepared us for this very thing is God, who also has given us the Spirit as a guarantee.
So the resurrection that we hope for when Jesus comes back is actually already in us. We just can’t see it now (because it’s in us), but it will be revealed in our bodies in that day. That’s why the resurrection is called “the revealing.”
Romans 8:19 NKJV
For the earnest expectation of the creation eagerly waits for the revealing of the sons of God.
So we do not hope (expect) to get something more when Jesus comes back. We only hope for the revealing of what we do not now see!
Romans 8:25 NKJV
But if we hope for what we do not see [not for what we don’t have], we eagerly wait for it with perseverance.
