...And the mouth movement didn't match the singing.
The worship band was lip-syncing! (Our pastor friend did say that the closing songs were live). I won't speculate as to why they didn't sing live, but I will say that this scripture immediately came to mind
13 Stop bringing meaningless offerings!
Your incense is detestable to me.
New Moons, Sabbaths and convocations—
I cannot bear your worthless assemblies.
14 Your New Moon feasts and your appointed festivals
I hate with all my being.
They have become a burden to me;
I am weary of bearing them.
15 When you spread out your hands in prayer,
I hide my eyes from you;
even when you offer many prayers,
I am not listening.
Jon Foreman sings about it here:
Ouch! I may not be lip-syncing, but how often are my lips singing along, but my mind is running through my list of things to do, planning my grocery list, or worse.
Psalm 19: 14 May these words of my mouth and this meditation of my heart
be pleasing in your sight,
Lord, my Rock and my Redeemer.
