Although there is no perfect knowledge of God, we can know that God exists by His effects. Those effects are not proportionate to God himself yet from every effect the existence of God can be demonstrated. We mustn’t think in our being able to demonstrate God exists from his effects that we can perfectly know God as He is in His essence.
This greatly refutes the idea that because God is not proportionate (God is infinite and His effects are finite, therefore there is no proportion) and it is wrongly assumed that a cause cannot be demonstrated by an effect not proportionate to it, which if believed, seems that the existence of God cannot be demonstrated.
The Apostle Paul says, “The invisible things of Him are clearly seen, being understood by the things that are made” Romans 1:20
Things that are made in and of themselves demonstrate a maker. Intelligent things assume an intelligent designer. In fact, we are so smart we can undo ourselves, unlike the brutes.
