The last command/is all but Love, O let this last will stand! is true, and Donne could clearly omit the definition of love: for that was within the command. We are to love as Christ did, who gave himself unto death for those whom he called to himself. To quote a modern Hillsong lyric.
To reveal the kingdom coming
And to reconcile the lost
To redeem the whole creation
You did not despise the cross
For even in Your suffering
You saw to the other side
Knowing this was our salvation
Jesus for our sake You died
Jason Ingram, Brooke Ligertwood and Scott Ligertwood are good craftsmen and craftswomen, but they are not Donne. They have not plumbed the depths Donne did, nor have they ascended to the heights he did following.
And he says those of faith sit with Christ in the juncture of the Knotty Trinity. Through Christ’s Love for us, which means that we will take up our cross, the cost of our love.
Father, part of His double interest
Unto Thy kingdom Thy Son gives to me;
His jointure in the knotty Trinity
He keeps, and gives to me his death’s conquest.
This Lamb, whose death with life the world hath blest,
Was from the world’s beginning slain, and He
Hath made two wills, which with the legacy
Of His and Thy kingdom do thy sons invest.
Yet such are these laws, that men argue yet
Whether a man those statutes can fulfil.
None doth; but thy all-healing grace and Spirit
Revive again what law and letter kill.
Thy law’s abridgement, and Thy last command
Is all but love; O let this last Will stand!
