Here it is set to LEONI by Meyer Lyon.
The God of Abraham praise,
Who reigns enthroned above;
Ancient of everlasting days
And God of love.
The Lord the great I AM!
By earth and heaven confessed;
We bow and bless the sacred name
Forever blessed.
The God of Abraham praise,
Whose all sufficient grace
Shall guide us all our happy days
In all our ways.
He calls us each a friend;
He calls himself our God.
And he shall save us to the end
Through Jesus’ blood.
He by himself has sworn;
We on his oath depend.
We shall, on eagle wings up borne,
To heaven ascend.
We shall behold his face;
We shall his power adore
And sing the wonders of his grace
Forever more.
The God who reigns on high
The great archangels sing,
And “Holy, holy, holy!” cry,
“Almighty King!”
Who was and is the same.
And evermore shall be:
the Lord, our Father, Great I AM!
Eternally.Before the Saviour’s face
the ransomed nations bow,
all praising his almighty grace,
forever new.
He shows his wounds of love,
they kindle to a flame
and sound through all the worlds above
the slaughtered lamb.The whole triumphant host
Give thanks to God on high.
“Hail, Father, Son, and Holy Ghost!”
They ever cry.
Hail, Abraham’s God and mine!
I join the heavenly lays:
All might and majesty are thine
And endless praise!
