I feel so offended when reading of Christians fighting Christians. North Ireland confounds me. I know there is as much economic and political strife as religious division there, but if we were living out our faith as Catholic Christians and Protestant Christians, we would know that the essence of our faith means to love one another, not kill one another. But Paul is not finished. He wants to go deeper yet, so he moves from our love to the source of all love in Christ's love for us.
Lovers are people who have been loved.
And if someone has missed out on love from their family, they need to know even more the love of Christ and the love of the family of God. There is a puzzle here. Love is the infinite that is beyond knowing. All else passes away, love remains. To elaborate on the scope of this love Paul speaks of it as having four dimensions.
