God is the One True God.
God is jealous for His relationship with His people because He passionately loves them and does not want them to be destroyed by idolatry.
He desires exclusive devotion and worship. To do less would make Him less than God.
“Do not worship any other god, for the Lord, whose name is Jealous, is a jealous God.” Exodus 34:14
Pray for Vietnamese to seek and find God Almighty and worship Him alone.
“Yet a time is coming and has now come when the true worshipers will worship the Father in the Spirit and in truth, for they are the kind of worshipers the Father seeks.” John 4:23
