Hello every1

[amm289807]

I'm looking for a song with the following lyrics:

"How can you recognize a child of God (repeat 3 X)
                       - or -
How do you recognize a child of God (repeat 3 X)
That's been washed in the blood of the Lamb
Ohhhhh hallelujah, hallelujah I've been washed in the blood of the Lamb.  Ohhhh hallelujah, hallelujah a child of God I am..."

It a group singing who I believe are young adults or children.

Thanks for any help provided
