God does not need the Creation in order to have something to love, because within Himself, love happens. Have you ever been so caught up in something that you just had to share it? That's because real love creates a genuine openness. The reason that we long for intimacy, is because we are made in the image of perfect intimacy.
Our King clothes Himself as a beggar and renounces His Throne, in order to win the hand of His bride. The Incarnation, the life, and death of Jesus answers once and for all the question, "What is God's heart towards me?" This is why Paul says in Romans 5, "Look here, at the Cross."
I want you to think about the part you find yourself playing, the self that you put on like a costume. Who cast you in this role? Are you living out a script that someone else has written for you? Most of us have not been invited to live from our hearts, to be who we truly are, so we put on the costume hoping to offer something acceptable to the world, something functional. Either we're chosen for the wrong reasons, or we're not chosen at all.
So what does this have to do with our heart?
Answer:
"What is man that You are mindful of him,
the son of man that you care for him?
You made him a little lower than the heavenly beings
and crowned him with glory and honor." (Psalms 8:4-5)
