Charles Spurgeon Commentary 1 Corinthians 15:37-38

"and that which thou sowest, thou sowest not the body that shall be, but a bare grain, it may chance of wheat, or of some other kind; but God giveth it a body even as it pleased him, and to each seed a body of its own." — 1 Corinthians 15:37-38 (ASV)

Every person will have their own body. There will be differences and unique characteristics, just as there are here; and we will therefore know each other.
