Hebrews 11:6

But without faith it is impossible to (walk with God and) please Him, for whoever comes (near) to God must (necessarily) believe that God exists and the He rewards those who (earnestly and diligently) seek Him. 

Seeking God is a vital faith builder. When seeking something, we try to learn all we can about the subject. The more we know and increase our knowledge, the more our faith will build. God is a rewarder of those who seek Him in faith. How close we get to God depends entirely on our commitment to learning more about Him.
