When Psalms 100:1 says, “make a joyful noise to the Lord all you lands” I believe that it is saying that we should give a loud shout to the Lord and praise His name. In my opinion, the fact that it says “all you lands” declares that since in every land the Lord’s goodness is seen in every land His name should be praised. In Psalms 100:3 it is declaring that the Lord alone is God and that there is no one else and that we are His people and He is our God.
Since God is gracious I believe that Psalms 100 is teaching us that He deserves our praise and He should be praised with gladness and a loud shout. We should always give praise to God and remember that He alone is worthy and we should remember that His goodness and mercy is everlasting. Ephesians 1:6 says, “To the praise of the glory of his grace, wherein he hath made us accepted in the beloved.”. So from that we know that we as Christians are accepted into God’s family. Amen
