I waited patiently for the LORD; He inclined to me and heard my cry. He drew me up from the pit of destruction, out of the miry bog, and set my feet upon a rock, making my steps secure. He put a new song in my mouth, a song of praise to our God. Many will see and fear, and put their trust in the LORD. (Psalm 40.1-3)
I spoke about this yesterday, but I'd like to reiterate it here. For those in whom salvation has taken root, who have experienced the pit-defying rescue and the solidity of the Rock underfoot, singing is a natural result.
It's not the only result. It, like other fruit from the True Vine, can be fabricated, faked, feigned. But those who have been delivered do have a song in their mouth, a song of praise to their rescuing, delivering, security-ensuring God.
So how about you. What song are you singing?
But that's just me thinking thoughts...
