But without faith it is impossible to please him: for he that cometh to God must believe that he is, and that he is a rewarder of them that diligently seek him.
Hebrews 11:6
To earnestly and diligently seek, desire and passionately pursue after God, one must have come to firm believe that God is. Now the challenge for those who have come to believe in God is this: why are they not in passionate pursuit after Him. It is one thing to come to faith in God but a different thing to earnestly and diligently seek Him. Rewards are promised only to those who diligently seek Him.
