Psalm 100 is psalm of praise and thanksgiving. Praise is giving honor to God for who He is. Thanksgiving is giving honor to God for what He does.
A quick review of this short psalm of only five verses tells us to do seven things:
Make a joyful noise unto the Lord, all ye lands. Even if you can't sing, make a joyful noise and shout unto the Lord. Raise your voice and acknowledge welcoming God as you would welcome royal into your midst.
Serve the Lord with gladness. Not only should we serve the Lord, but we should do it with gladness. Render honor to God.
Come before His presence with singing. Notice that our "joyful noise" in verse 1 has turned to "singing" in verse 3. Our shouts have turned to song. Our songs are not to create our gladness, but to express it. Through our singing we approach God.
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. Know that the Lord is God along with the other things this verse says. Acknowledge that the Lord is God. Here we acknowledge that Jesus is our Savior and submit to him as Lord.
Enter into his gates with thanksgiving, and into His courts with praise. Thanksgiving is through the gates and praise is in His courts. The psalmist uses the temple as an analogy to inform us how we can open the door into God's presence. The gates were a part of the outer wall that surrounded the temple grounds. One entered the temple complex through the gates. As we enter God's presence we enter His gates with thanksgiving. Once through the gates, the worshiper enters the courts with praise. Here we extol God for who He is. One gets a sense of movement from the outside to the inside, moving closer to the presence of God.
Be thankful unto Him. Be thankful for all God has done for you. Notice the repetition in verse four. Giving thanks to God and praising Him are stated twice. It is repeated so that we will not miss its importance.
And bless His name. The Lord's name should always be blessed. Praise his name. True worship always involves falling at the feet of God.
The last verse tells us why we should do the above seven things: "For the Lord is good; His mercy is everlasting; and Hs truth endureth to all generations."
When studying Psalm 100, we learn that God is willing to meet us anywhere, anyplace, and anytime, but we need to come into His presence. Psalm 100 shows us the pathway into God's presence, much like a procession to visit a dignitary or protocol to visit a king.
As you meditate today, also visualize yourself in that procession visiting the King of Kings and the Lord of Lords.
