Could be Al Green, but don't think so.

Lyrics:
The Father sent His son to die for us
So He could give you His blessing
So to give up your sin is not too much
For Him to give you His blessing

I am a witness, I am a witness

So with your hands raised to the sky
Praising the Lord cause He's most high
Don't be afraid and don't you hold back
Cause praising the Lord is really where it's at

I am a witness, I am a witness

I love Him myself, Jesus is my Lord

Thank you,

Have you checked to see if it could be Bobby Womack? He and Al Green
Sound very much alike and both sing Gospel these days.

Here's information on one of his albums, just in case:
