Not only do we know what our present bodies are like, we also have an example in Scripture of what a resurrection body is like. We’re told a great deal about Christ’s resurrected body, and we’re told that our bodies will be like his.
The Lord Jesus Christ . . . will transform our lowly bodies so that they will be like his glorious body. (Philippians 3:20-21)
Beloved, we are God’s children now; it does not yet appear what we shall be, but we know that when he appears we shall be like him, for we shall see him as he is. (1 John 3:2)
