God has made provisions for our happiness here and now. The One who created our bodies created all of the laws of nature that would help us to function optimally if we would live in harmony with them. Jesus said, "I have come that they may have life, and that they may have it more abundantly" (John 10:10). How wonderful that He desires us to live abundant lives!
In the sidebar to the right we share some resources on abundant living. May you be blessed!
