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. (Hebrews 11:6, NIV)
Every act of worship is the fruit of faith.
To worship, we must believe that:
God exists, and
as we respond to Him,
He will respond to us;
He calls us to worship Him in spirit and in truth;
He is self-existent,
while we depend entirely on Him;
His authority is so absolute and His perfections so infinite that
we must put all we are under His control now and forever; that
we justly owe Him every thought, word, and deed.
To worship is to believe these truths and to live accordingly.
