Isaiah 48:18

Oh, that you had paid attention to My commandments! Then your peace and prosperity would have been like a (flowing) river, and your righteousness (the holiness and purity of the nation) like the (abundant) waves of the sea.

Faith and obedience to the word of God go hand in hand.  We will not be obedient to the commands of God unless we believe in His word.  Our peace and our prosperity depend upon what we believe.  The word of God reveals unto us how we are to handle the circumstances of life.  God’s greatest desire is that we would turn to Him and that He could then bless us according to His word.
