What do spirits do while waiting for the Resurrection?
If someone dies today, and their spirit is with God in Heaven, what do we know about their time? All we know are little glimpses we see in Scripture, mostly moments of worship. That does not mean though that is their only focus.
We can assume it is only the important moments such as worship, which are the ones we have been shown in scripture. We don’t see what it’s like to do recreation or fellowship.
Paul says in 1 Corinthians 2:9
1 Cor. 2:9 However, as it is written:
“What no eye has seen,
what no ear has heard,
and what no human mind has conceived”—
the things God has prepared for those who love him—
There is a true mystery surrounding that future. It’s like a gift on Christmas, intentionally kept under wraps to heighten our anticipation and excitement about it. It's also probably impossible for God to wholly explain it to us. We will just have to see it to experience it.
But none of those spirits up in Heaven now will be wishing they can come back and be part of life down here again. They are happy to be where they are – and we will be too!
