Psalm 100 21st Century King James Version (KJ21)

1 Make a joyful noise unto the Lord, all ye lands!
2 Serve the Lord with gladness; come before His presence with singing!
3 Know ye that the Lord, He is God; it is He that hath 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 unto Him, and bless His name!
5 For the Lord is good, His mercy is everlasting; and His truth endureth to all generations.

Prayer

Lord Jesus praised be your name, we are your servants, we ask you to lead us to each of us in your ways and status, without deviating to right or left. Save us from this world that is contaminated more every day and denies your name, we are in this world Lord but we are not his. We call on you, Lord, to send your Holy Spirit, in order to convince all the chosen ones of sin, turning away from evil and guarding us from our enemies. We ask this in the name of your beloved son, Jesus Christ. Amen.
