Psalm 100

Make a joyful shout to the Lord, all you lands!
2 Serve the Lord with gladness;
Come before His presence with singing.
3 Know that the Lord, He is God;
It is He who has made us, and not we ourselves;
We are His people and the sheep of His pasture.

4 Enter into His gates with thanksgiving,
And into His courts with praise.
Be thankful to Him, and bless His name.
5 For the Lord is good;
His mercy is everlasting,
And His truth endures to all generations.

PRACTICAL APPLICATION:  this is a short Psalm has many guides for our spiritual life:  serve the Lord and His Church gladly, acknowledge God as master and creator, always give thanks to Him for His blessings and joyfully praise Him when we go to church.
