The fatal flaw of human wisdom is that it promises that you can change your relationships without needing to change yourself. Every painful thing we experience in relationships is meant to remind us of our need for God. And every good thing we experience is meant to be a metaphor of what we can only find in Him.. We settle for the satisfaction of human relationships when they were meant to point us to the perfect relational satisfaction found only with God.
If I am seeking to get identity from you,I will watch you too closely, listen to you too intently, and need you to fundamentally. I will ride the roller coaster of your best and worst moments and everything in between. And because I am watching you too closely, I will become acutely aware of your weaknesses and failures. I will become overly critical, frustrated, disappointed, hopeless, and angry. I will be angry not because you are a sinner but because you have failed to deliver the one thing I seek from you: identity. But none of us will ever get the well-being that comes from knowing who we are from our relationships. Instead we will be left with damaged relationships filled with hurt, frustration and anger.
Our purpose (in relationship) is to get what we want but God's purpose is to give us what we really need. We think things are going well only if we are getting along with others. But God says that it is also when we are not getting along with others that he is accomplishing his purpose. God has designed our relationship to function as both a diagnosis and a cure.
We all look for strategies or techniques that will free us from the pain of relationships and the hard work good relationships demand. We hope that better planning, more effective communication, clear role definitions, conflict resolution strategies, gender studies, and personality typing--to name just a few -- will make the difference. There may be value in these things, but if they were all we needed, Jesus' life, death, and resurrection would be unnecessary or, at best, redundant. Skills and techniques appeal to us because they promise that relational problems can be fixed by tweaking our behavior without altering the bent of our hearts. But the Bible says something very different. It says that Christ is the only real hope for relationships because only he can dig deep enough to address the core motivations and desires of our hearts. Most dangerous aspect of your relationships is not your weakness, but your delusions of strength. Self-reliance is almost always a component of a bad relationship.
