Our relationship with God is revealed by how we interact with him. If you only think of him once in a while, then obviously, you hardly know him. On the other hand, if you know that he is your loving Father who will always help you and that nothing is impossible with him, and are always aware of his presence, are open to him, share everything in your heart with him, and ask boldly for what you need in serving him, then you are most likely in union with him already. The point I want to make is that God is not to be approached timidly, but boldly with full confidence and no hesitation. Being infinite, omnipotent, and most loving, he surely can handle everything you "throw" at him. An intimate relationship is developed when you open up to God and share everything with him.
