Hmmm....let's see.
According to I Corinthians 15, we will be changed in an instant at the resurrection. Our bodies will be changed at that time from the corruptable bodies we have now to incorruptable. In Revelation 21:4, it says that "...there shall be no more death, neither sorrow, nor crying, neither shall there be any more pain: for the former things are passed away." for "there shall be no more curse" (Rev 22:3). Our bodies will be perfect, as we are being perfected by the Spirit now. We will be in perfect harmony in body, mind, and spirit.
"Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is." - I John 3:2
This indicates to me that we will be like Jesus. So the best example we can turn to is the portions of scripture after His Resurrection.
"And after eight days again his disciples were within, and Thomas with them: then came Jesus, the doors being shut, and stood in the midst, and said, Peace be unto you.
Then saith he to Thomas, Reach hither thy finger, and behold my hands; and reach hither thy hand, and thrust it into my side: and be not faithless, but believing. And Thomas answered and said unto him, My LORD and my God." - John 20:26-28
It is evident that Jesus had some physicality to him, for He still had the marks on His hands, feet, and side from the crucifixion. He further demonstrated this by eating fish and honeycomb in Luke 24:42, proving that He was flesh and bones (Luke 24:39).
Yet He had abilities that go beyond normal fleshly means. For example, he was able to appear (Luke 24:36, John 20:26), behind closed doors, and disappear (Luke 24:31), suggesting the ability to teleport. And He was able to disguise himself (Luke 24:13-16, John 20:14-15). And finally, He could rise up in the air (Acts 1:9). My guess is that if we are going to be as He is, we will inherit these abilities also. Why?
I have a theory.
When the Sadducees confronted Jesus about the Resurrection, seeing as they didn't believe it, they asked about whose wife would a women be after being married successive number of times. What Jesus said was profound:
"The children of this world marry, and are given in marriage:
But they which shall be accounted worthy to obtain that world, and the resurrection from the dead, neither marry, nor are given in marriage: Neither can they die any more: for they are equal unto the angels; and are the children of God, being the children of the resurrection." - Luke 20:34-36
So it stands to reason that we might possibly function like angels in the afterlife, as ministering spirits (Hebrews 1:14). I do not believe that we will be just sitting around playing on our harps all day. No, I think God will have work for us to do, but it won't seem like work, certainly not in the tedious task that the curse brought on us. I think we will be glorifying God in our work in heaven by ministering to those in need.
But if we are in heaven, who would we minister to?
Ahh...this is where it gets dicey and where my theory really comes into play. And from this point on, I take some liberties for conjecture.
My Sci Fi side now kicks in, for I am not so naive to think that there is no possibility that we are alone in this vast universe. And that God might have created life on some other world somewhere in the Cosmos. Certainly, God can do whatever He wants, right? All things are possible.
Suppose for a moment that He did. Would it be too out of line to think that perhaps another world could be populated creature made in the likeness of God, and that they are experiencing the same kind of situation that we are in. Maybe with the same need for salvation and restorations we need. And that He has need of angelic beings, "sent forth to minister for them who shall be heirs of salvation" in that world. And what if He uses us as ministering spirits.
Farfetched. Maybe. But what else are we made for but to love others, giving drink to the thirsty, and encouragement to the hurting. Most of the descriptions of angels show them in human form, such as when Jacob wrestled with one. Hebrews 13:2 tells us that we may inadvertently be entertaining angels unaware. Maybe strangers you've met we actually angels.
Are we not going to judge angels? (I Corinthians 6:3) Which angels? Well, I think fallen angels are already judged to the bottomless pit. And if God created angels in their current form, they are doing the perfect will of God anyway, so what's to judge.
However, if angels were once like us, then our judgement toward them would be a human judgement, of how well they ministered to us.
Just some food for thought. Eat at your discretion.
