Ephesians 5:19: Making melody in your heart to the Lord

Howe'er untunable the voice
The heart doth most melodious prove,
When skill'd in Jesus to rejoice,
And glory in His dying love:
Exulting in its Saviour's grace
The Lamb's triumphant song it sings,
Presents the quintessence of praise,
As music to the King of kings.

Hymn'd by the bright angelic choirs,
The King of kings approves their strain,
Hearing amidst their sweetest lyres,
The Spirit of His love in man.
Now, Father, now incline Thine ear,
The music of Thy Spirit own,
And in my heart delight to hear
The voice of Thy acclaiming Son.
