1 Blest Instructor! from Thy ways,
Who can tell how oft he strays!
Save from error's growth my mind;
Leave not, Lord, one root behind.
2 Purge me from guilt, that lies
Wrapt within my heart's disguise;
Let me thence, by Thee renewed,
Each presumptuous sin exclude.
3 Let my tongue, from error free,
Speak the words approved by Thee!
To thine all-observing eyes
Let my thoughts accepted rise.
4 While I thus Thy Name adore,
And Thy healing grace implore,
Blest Redeemer, bow Thine ear!
God, my Strength, propitious hear.
