1. Thought by thought we are building for eternity,
Stubble, wood or hay, of stubble, wood, or hay;
Thought by thought we are building for eternity,
Structures that will fall or stand in that great day.

Refrain
We are building on the rock,
We are building on the rock,
On the rock of ages, Christ our only hope;
Firmly building on the rock,
Firmly building on the rock,
On the rock of ages, Christ our only hope.

2. Act by act we are building for eternity,
Silver, precious stones, or of the purest gold;
Act by act we are building for eternity,
Lives that will gain entrance to the heav’nly fold. [Refrain]

3. Deed by deed we are building for eternity,
On the firm foundation, Christ the solid rock;
Deed by deed we are building for eternity,
Everlasting hope beyond earth’s storm and shock. [Refrain]
