Yes, God has a purpose for His Creation. First, we can be sure that God-Consciousness is not going to go to the trouble of creating a universe without a reason. Second, His main purpose appears to be to have experiences. Without a Creation of some description, God-Consciousness would be like a very bored dreamer who had nothing to dream about. Experience and interest require something to experience and be interested in.
Without His Creation, God-Consciousness would be nothing but eternal nothing and some idle musings about nothing. So, God’s first purpose in creating the universe was to add experience, expression, and enjoyment into His Life. God-Consciousness experiences what it is to be a grain of sand on the beach, to be the Sun that warms it, and the wave that cools it. He is the child who puts it into a bucket and He is the bucket. How much experience, expression, and enjoyment can He take?
Another purpose is to experience His Creation learning to see through the futility of Ego and evil. From God’s perspective, it is all experience, and at the same time it is all illusion (maya); it would be very rewarding to see His Creation, and humanity in particular, realise the Truth and then to voluntarily relinquish Ego and duality. A key mechanism towards this realisation is relationship. In forming a deep intimate or spiritual relationship with other people, we experience a deeper relationship with ourselves, and so a deeper relationship with God, to the point where we can realise our Oneness with God, and so come to the self-realisation of our own true Being.
Since God-Consciousness is all there is, the idea of the Creation being there specifically to praise God is nonsense. God-Consciousness does not need to praise Himself to be fulfilled. Nevertheless, praise that is heartfelt appreciation of our lives and our experience (God-Consciousness’ life and experience) does not go amiss. It is just appreciation and recognition. However, it is not the purpose of God’s Creation. The purpose of God’s Creation is to experience.
