In my experience, WORRYING is GOD'S TOOL TO LET ME KNOW THAT I NEED TO UP MY FAITH: "Do I trust Him or not? Is He faithful or not? Is His Word true or not? Clearly, the Lord wants to grow our faith and give us clarity in His word. LET HIM, THEN THANK HIM.
My brother-in-law sang this to my husband and (now) mother-in-law for their dance at our wedding. This is already a special phrase/song but that moment in time made it all the more special. What a Wonderful World indeed!!!
