Go tell it on the mountain,

Em            G
When I was a seeker
Em                       G
I sought both night and day,
Em                   G
I asked the Lord to help me,
A                     D
And he showed me the way.

Over the hills and everywhere,

Em             G
He made me a watchman
Em              G
Upon that city wall,

And if I am a Christian,
A                  D
I am the least of all.

That Jesus Christ is born.
