God is a Spirit, just and wise
He sees our inmost mind;
In vain to Heav’n we raise our cries,
And leave our souls behind.

Nothing but truth before His throne
With honor can appear;
The painted hypocrites are known
Through the disguise they wear.

Their lifted eyes salute the skies,
Their bended knees the ground;
But God abhors the sacrifice
Where not the heart is found.

Lord, search my thoughts, and try my ways,
And make my soul sincere;
Then shall I stand before Thy face,
And find acceptance there.
