“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.” ~ Heb. 11:6
There is more to Biblical faith than believing in the existence of God. The devils believe that. We must not only believe that “God is,” that is, He is all He says He is. But we must also believe He is a prayer-answering God. This is the second wing that gets our text off the ground, and soaring into Heaven to the throne of God.
Once God's existence is believed in, of necessity, we must expect Him to hear and answer our prayers. God's recompense for true faith is always a reward. Each of the twenty-two or so names found in God's hall of faith, in Hebrews eleven, received some sort of token from God for his or her faith.
But, whatever the remuneration, it doesn't hold a candle to the reward of God Himself. For our God has said to all those with legitimate faith, "I am thy…exceeding great reward." Orphans enjoy gifts, but would gladly give them all up for a father.
To have Christ is everything; and everything is nothing without Him.
