They are bruises on the neck, though my first thought would be a collection of songs by the band the Buzzcocks. However, it is also a statement of fact. Love does indeed bite.
You can welcome its incision, or try and avoid it, but it is something that gets you. It becomes part of you and changes you. It brings out aspects of who you are like nothing else can – but it opens you up to vulnerability and all kinds of other emotions you may not have been expecting.
The Greeks, quite sensibly, knew you couldn’t sum it up in just one word – there are distinct aspects of it. They reckoned four. Read C S Lewis, the Four Loves. Or attend the next four Ignite services. Or do both.
Paul’s message in writing the 13th chapter of his first Corinthian letter could be summarised by saying if God’s love hasn’t bitten you to the core, you’ve not really known its possibilities and eventualities.
He wrote it so that you might understand that that is how the life of God works, and that you would be open to it, and delight in it.
