To worship God in spirit and truth means that we must come to God on a spiritual level without pretense, or hypocrisy. To say that we must come to God on a spiritual level is not to say that we cannot connect with God physically, emotionally, or intellectually, but that what we are to know of God comes out of the spiritual and infiltrates all of our other senses. So then, worshipping God takes a spiritual connection.
In order for us to come to the place where we worship God spiritually, God must awaken our spirits. It is then that we are able to relate, connect, and worship God out of a spiritual place and not one of intelligence, emotion, or the physical condition. Once this happens, we are prepared to worship God in truth.
We can worship God in truth because we have connected with Him as He is – spiritual. Because we connect with Him on a spiritual level, we then begin to understand how to worship Him so. The word “truth” tells us that we must worship honestly, openly, sincerely, and without pretense or hypocrisy. When we connect with God spiritually we begin to understand some of what it means to worship God that way. When God reveals Himself to us He includes His will and desires; not all at once, but gradually. God relates to us in truth and desires that we respond in kind. When He reveals Himself, He reveals that He wills for us to worship Him and how we are to worship Him. This is the spiritual and truthful worship of God.
