In 1 Thessalonians, the writer tells us that that God's peace will sanctified us wholly or completely. We sometimes get the idea that God just wants to save our soul, but the word tells us that God is interested in our whole self - body, soul and spirit. We see that in the gospels, Jesus healed many people. While he did this to show his power on earth and to fulfill prophecy, but also to reveal to us that if Jesus can heal us outwardly, He can heal us inwardly as well. Jesus used the miracles to show us that the kingdom of God is present and that promise is still true today.
