Psalm 100 is the only time the word "thanksgiving" is used in the headings of the Psalms. It probably refers both to sacrifice and attitude and is often linked with the word "praise". The entire Psalm speaks to the joyful response to life, seeking to praise God for all that He has done and for all that He is. The Psalm is in two sections: one a call to joyful worship and then the call is reiterated, finally stating the reasons for such worship.
Unrestrained joy and gladness pulsates through the first verses and "all the earth" is summoned to join the celebration, making it missional also. The word "worship" can also be translated "serve" as we have discussed before. It is worship exceeding just the gathering of God's people by emphasizing walking in the Lord's ways, loving Him, keeping His commandments and living a life consistent with our commitment to the Lord.
The reason for such worship is spelled out in v. 3. with the word "know". This is not head knowledge, but to experience and know in relationship. Imagine . . . we . . . His people! For our faith to remain vibrant we must never lose that sense of amazement and awe. In the time to come all offerings will cease, except the thank offering. All prayers will cease, except the prayer of thanksgiving. Several of our hymns are versions of Psalm 100. This Psalm takes us close to the heart of true worship, with congregations experiencing many different versions and forms of Psalm 100. mjm
