Today I would like to look at Psalm 100 verse 1 to 3
1)Sing to the LORD, all the world!
2)Worship the LORD with joy; come before Him with happy songs!
3)Acknowledge that the LORD is God. He made us, and we belong to Him;
we are his people, we are His flock.
To serve the Lord brings joy, therefore Christians must be happy and sing to honor the Lord. This also brings a confession that the Lord is our God. This further lead to the confession that we belong to God and that He created us. The image that we are God's flock, show us the intimate relationship between God and his children, who will be saved by Him.
Have a wonderful day.
Soli Deo Gloria
