Isaiah 8:20: Doctrines, experiences to try

Doctrines, experiences to try,
We to the sacred standard fly.
Assured the Spirit of our Lord
Can never contradict His word:
Whate'er His Spirit speaks. in me.
Must with the written word asjree;
If not — I cast it all aside.
As Satan's voice, or nature's pride.

The test of truth and righteousness,
O God, Thy records we confess.
And who Thine oracles gainsay
Have miss'd the right celestial way:
Their pardon sure they vainly boast,
In nature sunk, in darkness lost;
Or if they of perfection dream,
The light of grace is not in them.
