Faith in God

Proverbs 3:5-6 is my own definition of Faith in God.

Trust in the LORD with all your heart, and do not lean on your own understanding; In all your ways acknowledge Him,  and He shall direct your paths. (Prov 3:5-6)

Why must I trust God?  Because "without faith it is impossible to please Him, for he who comes to God must believe that He is, and that He is a rewarder of those who diligently seek Him." (Hebrew 11:6)
