When you begin to feel joy welling up within you for no reason, and for every reason, you will know that you have arrived at a place of deep connection with God. Until then, you should be continuously striving to know him more intimately, and more profoundly.
You should be seeking him in prayer during every waking hour. You should be striving to become one with him so that you think his thoughts, speak his words, and do his deeds. You should become one with him for all eternity, and all eternities, and all eternities combined. In Jesus' name, Amen.
