Jesus, the Truth and Power divine,
Send forth these messengers of Thine;
Their hands confirm, their hearts inspire,
And touch their lips with hallowed fire.

Be Thou their mouth and wisdom, Lord;
Thou, by the hammer of Thy Word,
The rocky hearts in pieces break,
And bid the sons of thunder speak.

To those who would their Lord embrace,
Give them to preach the word of grace;
Sweetly their yielding bosoms move,
And melt them with the fire of love.

Let all with thankful hearts confess
Thy welcome messengers of peace;
Thy power in their report be found,
And let Thy feet behind them sound.
