James 2:26 As the body without the spirit is dead, so faith without deeds is dead.
God created us to be in three parts like He is, our immortal souls, our mortal physical bodies and our spiritual beings.
We need our spiritual side to fill our physical bodies and make us whole.
Our faith in God is not whole unless we have trusted Christ for our immortal lives, live our lives trying to do what is best physically and fulfilling our spiritual needs.
Be whole with Christ.
