Because God is a personal being, the laws of nature that we experience on a continual basis are the product of his efforts. They are good because they come from a good God and they are observable manifestations of his goodness.
Because God is a personal being, he must have personal reasons for making natural laws to serve as the general means by which he would providentially rule this world.
Because God is a personal being, he may at times work in a way that is contrary to the laws of nature which he has made. This is why there can be miracles. Additionally, he must have personal reasons for performing miracles, or actions that defy normal natural laws. Furthermore, he must have personal reasons for performing miracles in the past that he is not performing now.
Because God is a personal God, he loves and can be loved. He loves me so much that he has given me himself in the person of Jesus, God the Son. He loves me so much that he promises to work all things together for my good and ultimate conformity to the image of Christ. And therefore, I can and must love him too.
Because God is a personal being, he has personal reasons for why things happen to me as they do. He must have a personal reason for why he would miraculously regenerate me from spiritual death to spiritual life. He must have personal reasons for why he has left me in difficult situations and why he has delivered me from difficult situations, sometimes miraculously. Therefore, I can and must trust him.
There are many things that I don’t know about God. But I do know, because he is a personal God, that he is a God worth knowing, loving, trusting and serving.
