We could get some kind of idea of how complex relationships are (by God’s design, by the way) if God were to ask us questions such as (per C. S. Lewis): “How many hours are in a mile?” and “Is yellow square or round?”
Relationships are incomprehensible, yet they exist all around us in all 360 degrees. Close family relationships, especially, are what they are!
God scores a great victory when we finally move beyond mere necessary entanglement and a wing-it responsiveness to actually scratching our heads in wonder about them: “What ARE they?”, in the first place, and “Why are they in our life?” in the second place, and “Why are each of these people so utterly different from ME?”
What God is doing in and through all relational dynamics is big business with Him. He uses them in our lives for something now and for something even that is yet to be. In reference to them, He has called us to walk softly, marvel more, stay alert, and pray compassionately.
