Is God only concerned about your soul, not your body?
No, God is not concerned only with the soul. Scripture presents human beings as three-part: body, soul, and spirit. In 1 Thessalonians 5:23, the God of peace is asked to sanctify the whole person—spirit, soul, and body—and preserve all three. Therefore the body matters to God and is included in His preserving work.
Les explains that the idea God cares only about the soul and not the body is wrong. He teaches that we are a three-partite person: body, soul, and spirit. He avoids the word trinity because it could bring us too close to being like God, but he insists we are a three-part individual. To prove it from Scripture, he turns to 1 Thessalonians 5:23, where the God of peace sanctifies wholly and preserves the complete spirit, soul, and body. Les stresses this preservation is not for seventy years but for eternity. He adds that we will not be a viable entity in eternity until we get the body, and for people living today, we are body, soul, and spirit.
