Malachi 3:4: Then, Jesus, then, when seven times tried

Then, Jesus, then, when seven times tried,
Thy people saved and sanctified
Thy glorious character shall bear!
A chosen race of priests and kings.
Each his accepted offering brings.
The incense pure of praise and prayer.

Returns the age of golden days.
The vigorous energy of grace,
That in Thine ancient servants shone;
While God with constant smiles approves
The souls whom join'd to Thee He loves,
For ever perfected in one.
