The conversion of Mrs. Rich [wife of the owner of the Covent Garden Theatre]…in 1745 had given Charles Wesley the entry into the musical world of London. As many years passed he became something like a private chaplain to many of the celebrities of the day. Mrs. Rich says of one of his hymns in 1746, ‘I gave a copy of the hymn to Mr. Lampe, who, at the reading, shed some tears, and said he would write to you; for he loved you as well as if you were his own brother. The Lord increase it, for I hope it is a good sign. As to the sale of the hymns, he could give me no account as yet, not having received any himself, nor have I got my dear little girl’s.’ Charles Wesley knew [actor David] Garrick well, and probably met Handel at Mrs. Rich’s. The growing reputation of his own sons as organists and composers drew these ties still closer between the Methodist clergyman and the musical celebrities of his later life.

Jesus, Thou soul of all our joys,
For whom we now lift up our voice,
And all our strength exert;
Vouchsafe the grace we humbly claim,
Compose into a thankful frame,
And tune Thy people’s heart.

While in the heavenly work we join,
Thy glory be our whole design,
Thy glory, not our own:
Still let us keep our end in view,
And still the pleasing task pursue,
To please our God alone.

The secret pride, the subtle sin,
O let it never more steal in,
To offend Thy glorious eyes,
To desecrate our hallowed strain,
And make our solemn service vain,
And mar our sacrifice!

To magnify Thy awful name,
To spread the honors of the Lamb,
Let us our voices raise;
Our souls’ and bodies’ powers unite,
Regardless of our own delight,
And dead to human praise.

Still let us on our guard be found,
And watch against the power of sound
With sacred jealousy;
Lest haply sense should damp our zeal,
And music’s charms bewitch and steal
Our hearts away from Thee.

That hurrying strife far oft remove,
That noisy burst of selfish love,
Which swells the formal song;
The joy from out our hearts arise,
And speak and sparkle in our eyes,
And vibrate on our tongue.

Thee let us praise, our common Lord,
And sweetly join with one accord
Thy goodness to proclaim:
Jesus, Thyself in us reveal,
And all our faculties shall feel
Thy harmonizing name.

With calmly reverential joy,
O let us all our lives employ
In setting forth Thy love;
And raise in death our triumph higher,
And sing with all the heavenly choir,
That endless song above!
