An early poem somewhere in Christendom describes Jesus between ourselves and all others. Between ourselves and our loved ones, ourselves and our neighbors, ourselves and our enemies, between ourselves and everyone. At least it seems to me I've heard and even been familiar with something like that (I did find a parallel, and maybe the one I was thinking of, though not precisely the same thought as here).
I think this is a good sound way to look at our relationships with others. That somehow by the grace of God in the work of God in Christ and by the Spirit, Jesus is in a true sense to be the intermediary not only between ourselves and God, but also between ourselves and others. We see this truth taught in Ephesians and in the New Testament, at least by clear implication. We in Jesus are told to love our enemies, and we can only do as those in Jesus and Jesus in us by the Spirit. And this can help us in living godly and well in all our relationships.
This reality in Jesus can surely help us work through and resolve issues in ways that are pleasing to God. It doesn't relieve us of responsible steps we need to take, including confession and asking for forgiveness, along with working at understanding just what God's revealed will is for us today in given situations. But it does provide the needed dynamic by the Spirit to carry this out, and see it through to the end.
I know this is a bit obscure, and hardly easy to understand even with simple words. What thought would you like to add here?
