Hebrews 11:6 (NIV)
And without faith it is impossible to please God, because anyone who comes to him must believe that he exists and that he rewards those who earnestly seek him.
Psalm 119:1-2 (NIV)
Blessed are those whose ways are blameless, who walk according to the law of the Lord. Blessed are those who keep his statutes and seek him with all their heart.
If we seek God with all of our heart, we will be blessed and God will reward us.
