This is a gathering prayer we wrote for the All Age venue at Spring Harvest 2023. We taught the response with these actions:

Every- (right arm out)

body's (left arm out)

wel- (right hand hug across chest)

come (left hand hug across chest)

God (right hand point up)

is (left hand point up)

here (both hands point down).

We did it to a beat, which led into the song "God So Loved" by We The Kingdom, but you could do it without music or leading into a different song.
 

Come everybody, gather to worship.
Everybody’s welcome, God is here! 

Come if you’re weary, hungry or thirsty.
Everybody’s welcome, God is here!

Bring your rejoicing, dancing and singing.
Everybody’s welcome, God is here!

Bring all your failures, questions and sorrows.
Everybody’s welcome, God is here!

All shapes and sizes, faces and backgrounds.
Everybody’s welcome, God is here!

All to the glory of Jesus our saviour.
[start quiet, getting louder:]
Everybody’s welcome, God is here!
Everybody’s welcome, God is here!
Everybody’s welcome, God is here!
