Hebrews 11:6 And without faith it is impossible to please him, for whoever would draw near to God must believe that he exists and that he rewards those who seek him. #Bible
Only God could come up with the concept of faith. To create a way back to Him for the rebellious fallen.
Faith allows us to see what is invisible and to know it exists. Even to know the Creator Jehovah in real time.
Faith insists that we believe in God and that he exists, and that we can draw near to Him, and through our faith He rewards those who seek Him.
Interestingly I believe as we grow in our relationship with God our faith moves into other directions as we realize we know God, and are more familiar with Him. Also our interaction with God becomes more intimate and personal as we discover He is already there when we become more aware of him. It never ends, God always satisfies whatever our need is completely.
Why would we stop growing with God? It would only retard our relationship.
