Questions and doubts be heard no more

Questions and doubts be heard no more,
Let Christ and joy be all our theme;
His Spirit seals his gospel sure,
To every soul that trusts in him.

Jesus, thy witness speaks within;
The mercy which thy words reveal
Refines the heart from sense and sin,
And stamps its own celestial seal.

'Tis God's inimitable hand
That molds and forms the heart anew;
Blasphemers can no more withstand,
But bow, and own thy doctrine true.

The guilty wretch that trusts thy blood
Finds peace and pardon at the cross;
The sinful soul, averse to God,
Believes and loves his Maker's laws.

Learning and wit may cease their strife,
When miracles with glory shine;
The voice that calls the dead to life
Must be almighty and divine.
