Angels are angels. People are people. Some like to play harps, but not everyone does.
“In the beginning [of time] God created the heavens and the earth.” (Genesis 1:1) In the end of time, God will recreate the heavens and the earth. (II Peter 3:13) At this pivotal recreation of reality as we know it, all will be restored to a righteous state of being. Righteousness is an elaborate word that means something or someone is as it/he/she ought to be. Oh, the wonderful thought of things being as they ought to be! We dream of bodies functioning as they ought to function, of minds thinking as they ought to think, and of relationships working as they ought to work. This spectacular condition of righteousness is the essence of Heaven.
God obviously knew what He was doing when He created all that is. Note from a thorough reading of Genesis chapters 1-3 that is human rebellion against God and His perfect plan which set into motion the disintegration of the universe, relationships, and people. When the same Jesus who entered the world to pay the price for human sunfulness returns again to the world, He will vanquish the curse of sin and reintegrate degree as we enjoy the heavens and the earth unhampered by human sinfulness and its dreadful consequences.
Redeemed people-redeemed by the blood of the God-Man, Jesus Christ-will always be people. We will not suddenly grow wings and don halos at the end of time. Our bodies will no longer be limited by space and time, and so traveling through the universe will no doubt come with ease! However, we will remain the humans we were always created to be. You know the saying, “God does not make junk.” We may be marred by our sin, but we are infinitely valuable as God’s creation. if we make the choice to allow Jesus to redeem us, we will function in the new heavens and the new earth with all the energy we always wanted, doing all the things we love to do. If Jesus made you to love walking and laughing, so you will! If-like me-He made you to love studying, speaking, and leading, so you will!
Heaven is an exciting place; it is more exciting than the best this sin-cursed earth has to offer. This old earth will be remade by Jesus, the same Jesus who remade our hearts when we asked Him to.
