"When you are praying, do not use meaningless repetition as the Gentiles do, for they suppose they will be heard for their many words." Matthew 6:7
Singing involves borrowing words written by someone else, and using them as your own, as a gift to honor God. Some equate repeatedly singing the same thing over and over again as praising, others say it symbolizes praying.
Praying initiates and perpetuates intimate conversation between The Father and His child. The words should be your own, and from your heart. Be careful borrowing what another man said to his wife, to impresses your own. They can tell when your heart isn't in it. God can too.
A beautiful Hallmark Father's Day card might appeal to the eye of the buyer, but it only takes the simplest scrawl from a child's crayon on a paper sack to reach a Dad's heart. Put your heart in what you pray.
TALK LESS! PRAY MORE!
