My God is so big so strong and so mighty there's nothing my God cannot (x2)
(do arms wide for 'big', then flex your arms for ‘strong and mighty’. ‘Nothing’ is done by wagging your finger or your flat hand palm down)
He made the trees, he made the seas, He made the elephants, too.
(arms wave in air like branches, make a wave pattern with your fingers for seas, and then make a trunk with your one arm for elephant)
My God is so big, so strong and so mighty, there's nothing my God cannot do.
(repeat above actions)
My God is so great so strong and so mighty there's nothing my God cannot do. (x2)
(same as above)
The mountains are his, the rivers are his, the stars are His handiwork, too.
(make a peak with the tip of your two hands touching, then conversely make a 'v' with your arms, and the stars are made by closing your fist and then opening it sporadically)
My God is so great, so strong and so mighty, there's nothing my God cannot do.
