As a final expression of communal worship, the thanksgiving hymn is ideal for congregational singing, or for the combining of choir and congregation (only here and there should this hymn be sung by the choir only). If the choir does sing this hymn, please note that they should never come to the front and face the congregation, as this gives the feel of a performance rather than worship.
This hymn is an expression of the congregation’s acceptance of God’s word, and provides an opportunity for collective praise and thanksgiving. It should be praise and thanksgiving-filled, energetic, and upbeat, thus creating an impactful send-off for the congregation. Just like with the opening hymn, these characteristics should outweigh the song’s connection to the sermon theme (although it can be very powerful when the song has these characteristics and is connected with the theme!).
Occasionally, it may be appropriate to repeat a song that was sung before the service or to sing the final verse of a hymn (worship hymn, acceptance hymn, etc. where maybe only one verse was sung previously). This reinforces the message of the hymn and can also help alleviate the strain of choosing (and singing) a large amount of music for each divine service experience.
