For perfect love I long have groaned, I would be wholly Thine; Yes, I would have the Lord enthroned In this poor heart of mine. Refrain: Come, Jesus, reign in me, My heart Thy throne shall be; Oh, tarry in Thy throne, ???Tis Thine, and Thine alone. All foes cast out, let this poor heart Be filled with love divine; Securely fixed, no more to part From this poor heart of mine. Let perfect love my portion be, To Thee my all resign; O Holy One, come dwell in me, And rule this heart of mine. No earthly language can express The love in Christ I find ???Tis boundless and it???s measureless, In this poor heart of mine.
