How important is it that we take advantage of this opportunity to consciously include God in all of our thinking? We will let Jesus Himself answer this question.
He is saying there that the purpose of the manifestation (the revealing, giving some the ability to see God) of the works of God in Christ is to produce faith.
Do we see God in His activities? Do we see God in His works? In the manifestation that Jesus spoke about there in John 6:29? Do we see God in His work? Do we see God in the physical creation? Romans 1 tells us very clearly that God's very power and authority - His very deity - is shown by His creation. All of that is nothing more than a type to help us to understand that by the physical works we can identify with this God and know that He is at work within His spiritual creation as well.
