It means letting the other grow and change. And it means opening yourself in truthful and vulnerable ways to the other. When those qualities are present in your relationships with others, you are blessed with a joy and intimacy that lets you be your most honest, vulnerable self. That special kind of intimate relationship is a glimpse, a taste of divinity. But as much as you long for it, you are also afraid of intimacy.
Love fails - which leads to frustration, hurt, and suffering.
That leads to fear of trusting again and being vulnerable with someone else who might be mean, or judgmental, or distant. But we are human, and are in human relationships. No human being can offer constant affection, no human being can enter into the core of our being and heal our deepest brokenness. It is worth the risk in order to experience those moments of empathy, support, honesty, and vulnerability. It is worth the risk to experience that connection, that deep relationship, to another - and even to risk an intimate relationship with God.
