What's in the heart of God? The simplest answer is also a biblical answer, God is love, but that answer is very difficult for mere mortals to believe. Not only because they die, but also the way they die-- disease, violence, predation, disasters-- love in the heart of God would never be posited by them as a reason for such. How could an all-powerful being, who loved us govern that way?
Then, there's the whole hell thing: everlasting torment, fire and brimstone, bulimic worms, and not so much as a tinge of pity from the God who's love. No matter how graphically (even at Mel Gibson levels) we paint a picture of Christ's vicarious sufferings, the idea of the lake that burns with fire is always going to trump that image and keep anyone from thinking of its imposition as arising from love. Is it any wonder that scoffers look at this subject with such incredulity?
But God either is or he is not. Even if our experience of life makes it difficult for us to believe that he is love if he is, there is no doubt that, if he is, he is incredibly smart! And yet, we who entertain the notion of God, constantly vie our intelligence against his, as if he, somehow, has to bow to our conceptions of sense and fairness. It's nothing new, we've been like that since the beginning of the human race. It's the very foundation of sin.
Christ said God was overjoyed to give us the kingdom, that he shares his secrets with the humble. Yet, we let our pride get in the way and argue with God, thinking ourselves capable of understanding what he alone understands. We glory in our own opinion, and it deafens us to God. We gain neither love or knowledge by it, only darkness. It's in the heart of God to love us and to share all his has and all he knows with us, but to receive it, we're going to have to get over ourselves and let God be the smart one.
