"Trust in him [God] at all times; ye people, pour out your heart before him: God is a refuge for us. Selah." -Psalm 62:8, KJV.

God knows exactly what is best for us, and He knows how to best deliver it to us. But, beyond knowing what is best for us, He has the ability to give it to us. Anything we can imagine about ourselves or what we want is nothing compared to what God has in mind for us. We need to simply trust Him.
