Here you go, Anna; from the United Methodist Hymnal:
1. All people that on earth do dwell,
sing to the Lord with cheerful voice.
Him serve with mirth, his praise forth tell;
come ye before him and rejoice.

2. Know that the Lord is God indeed;
without our aid he did us make;
we are his folk, he doth us feed,
and for his sheep he doth us take.

3. O enter then his gates with praise;
approach with joy his courts unto;
praise, laud, and bless his name always,
for it is seemly so to do.

4. For why! the Lord our God is good;
his mercy is forever sure;
his truth at all times firmly stood,
and shall from age to age endure.
