Open wide your mouth

Psalm 81:1-16
Sing for joy to God our strength shout aloud to the God of Jacob! Begin the music, sound the ram's horn on the day of feast.
The Lord has tested you at Meribah,  answered you out of thundercloud and rescued you in your distress. These are the story when Israelite went out of Egypt.
Open wide your mouth and I will fill it. You shell have no foreign god among your; you shall not bow to an alien god.
But my people would not listen to me. So I gave them over to their stubborn hearts to follow their own devices. their punishment would last forever.
If my people would listen to me, how quickly would I subdue their enemies and turn my hand against their foes! fed them with finest of wheat; with honey from the rock I would satisfy you.
This is a festival song. Refused by the Lord or choose trouble depends on your own heart.
Why?
The Lord has given us the promise if we follow his way and listen to him, he would subdue our enemies and fed us with abundant food even in impossible condition.
Open wide your mouth, means we shall has more faith to the Lord, his hands never shortened.
If the gospel has preached, but someone still does not listen it, then the Lord give them over their stubborn hearts to follow their own devices, then they will eat the result of their own sin.
How?
Open wide my mouth, sometimes we has little faith to the Lord, or we think too much or we shame to pray something, the Lord knows us everything, He like us talk with him, pray to him and sing for joy to God. He is my God almighty.
