It is because the Beloved is who the Beloved is that one at once becomes more enthralled in the pursuits of the Beloved as it is, in degree, directed towards the One Who Is Infinitely Lovable.
Such a pursuit attaches a portion of the Infinite to the Finite and beauty to what is not yet perfected. Love becomes a journey in the perfection process, not simply for gain of one's self but so also the whole world and all contained therein. It is there that we fill in what was in Christ's afflictions were 'lacking.' (cf. Col. 1:24) His Sacrifice lacks nothing except our participation, as St. Paul says, in the works that the Lord has "prepared for us to enter into." (cf. Eph. 2:10)
One's acceptance of imperfection is one of it being in the past, yet there is a perfection that we are called to in the same Spirit of the One Who Is. We mustn't be discouraged when faced with imperfection or imperfect love but, rather, be patient with the Other as He is patient with us. As the King is to his servant, so must we as his servants be patient to our fellow servants lest we be required to "pay to the last penny." (cf. Mt. 5:26)
This is the secret of love and mercy. We are called to be agents of change in this ineffable love. We are called to be agents of Love; we are called Disciples of Love.
May He be praised.
