In a sense, all Psalms are public psalms in that they are available to all but some are more suitable for corporate worship and corporate prayer as they look at issues of general interest and are not focused so much on the individual.
Psalm 104 the great song to the creator embodies the corporate aspect:-
‘O Lord, how manifold are your works! in wisdom you have made them all; the earth is full of your creatures.’
‘You send forth your Spirit and they are created, and so you renew the face of the earth.’
See if you can find other psalms which are aimed at being shared by the whole community.
Some will embrace themes we have looked at earlier in the week, praise: psalms 118 and 100, lament: psalm 86, memory: psalm 8.
Psalm 100 say:
‘Make a joyful noise unto the Lord, all the earth.’
As our final act, this week try writing a song or poem as praise to God which could be used in a service of public worship. Who knows we may end up with a collection of Turton Team Psalms!
