What faith knows it knows only by the Word of God, which is more sure and more certain than anything we learn by sight or experience. The Christian learns that what God reveals to him must be known and discerned by faith and not by sight. So it is with the resurrection of the body – what we know by faith overrides what we know by sight and experience. Our bodies will return to the ground (unless the Lord returns first), but we know by faith that He will raise that body to eternal life.
