Giving Thanks to the LORD!
This psalm is an exhortation for thanks offering to God and may have its roots in the “thank offering,” which is to be accompanied with exuberant joy. According to the Septuagint, it is a “psalm for confession,” or more readily a confession of appreciation or thanksgiving to God. It is the only psalm that is explicitly identified as "a psalm for giving thanks." The text before us gives us five movements in this psalm. The first imperative mentioned is "We Are to Make Some Noise to the LORD.” The text says:  “Make a joyful noise unto the LORD, all ye lands.” We are to come to church in order that we may shout. The original Hebrew word meant to make a “glad shout.” It is the type of shouting we do when we see someone we have longed to see and love.
Here is the point: we are not to be subdued in our worship or praise to God, because silent belief is not enough.
The second imperative: "We Are to Serve the Lord." The text says:  “Serve the LORD with gladness.” It is a byproduct of our joyful noises. We define “serve” here as worship. This psalm clearly suggests to us that we serve God by our worship. Paul the apostle in writing to the Roman believers echoes the same sentiment when he wrote: (Romans 12:1) (KJV) “I beseech you therefore, brethren, by the mercies of God, that ye present your bodies a living sacrifice, holy, acceptable unto God, which is your reasonable service.” Worship leads to service, and true service is worship.
Point: we give thanks to God by serving others!
The third imperative is "We Are To Come to Worship." The text says: “come before His presence with singing.” This means to come before His face with singing. (Psalm 95:6) (KJV) 6 “O come, let us worship and bow down: let us kneel before the LORD our maker.”
Worship requires work; coming requires little effort, and this Psalm teaches us what’s involved in worship. Here is the model for motivation: (read Psalms 63:3-7) (KJV).
Point: Yes, we are to come to church, but we are to come to church to worship God alone.
Now the fourth movement of the text is an indicative statement, meaning it is a statement of truth. "We Are to Make An Observation or Declaration Concerning the Lord God." The text says:  “Know ye that the LORD He is God.” It is alluding to something we are to be aware of without question, and that because of experience. (read Deuteronomy 4:39) (KJV). In other words, the LORD is both our Creator and our Savior.
Point: without this understanding, our worship will be futile.
When we get to verse four, the emphasis is unmistakably upon a congregation of people who are praising God together. Therefore, We Are to Accept the Invitation to Approach the LORD. The text says:  “Enter into His gates with thanksgiving, and into His courts with praise: be thankful unto Him, and bless His name.” It is emphasizing more than just individual worship and praise; we are invited to not only draw near to God, but to come into His gates. Gates offer a place of security. The root word for thankful here implies the acknowledgment or confession of sin; and the desire to express one’s public proclamation or declaration of God’s attributes and His works. The beauty of it is as James declares: (read James 4:8) (KJV). The expression of thanks to God is included in praise which means it’s not just saying thank you, it’s demonstrating it in our worship! So in His courts (a yard enclosed with a fence; a hamlet surrounded with walls) we enter with great exuberance.
Point: we offer praise, that is, we “boast” about the LORD; we bless His name – which is an act of adoration.
Finally, We Are to Make a Observation or Declaration About the LORD's Character. The text says:  “For the LORD is good; His mercy is everlasting; and His truth endureth to all generations.” This verse reminds us that we ought to give thanks to God not just for what He has done, but more so for Who He is! Read (James 1:17) (KJV); (Psalms 34:8) (KJV). Chuck Swindoll says: “Praise is the deepest expression of the soul in love with God;” maybe that's why so many people are quiet in church when they come to worship; maybe they really don’t love the LORD!
Even though we are living in changing times, there is something that is constant: (read Hebrews 13:8) (KJV). It gives us another good reason to praise His holy name!
Now what that means to you and me is this: He Will Always Be! And I invite you now to put it to the test!
Think on These Things:
Has God been good in the past? If we are honest we have to admit of course He has! To be honest, we have to change this question to the simple statement, “God is good!” That is because He is always good! You don’t have to worry that He might stop being good or change His good ways.
Has God been loving? Of course, He has! Again, we have to change this question to the simple statement, “God is loving!” Then rest assured He will always be loving! Because His very nature is love. You don’t have to worry that He will stop loving you. Has He brought you through difficult times? Of course, He has! Then rest assured He will always bring you through!
Has God been merciful? Of course, He has! Once again, we have to change this question to the simple statement, “His mercy is everlasting!” Then rest assured He won't give you what you deserve!
Has God been truthful? Of course, He has! Finally, we have to change this question to the simple statement, as did the psalmist: “His truth endures to all generations!” Then rest assured that His Word will never be changed? Because as (Isaiah 40:8) declares: (KJV) 8 “The grass withereth, the flower fadeth: but the word of our God shall stand for ever.”
Then take the time to shout with gladness this prayer: (Psalms 63:1-8) (KJV)
