"Eternal God, you are a mystery as deep as the sea; the more I search, the more I find, and the more I find the more I search for you. But I can never be satisfied; what I receive will ever leave me desiring more. When you fill my soul I have an even greater hunger, and I grow more famished for your light. I desire above all to see you, the true light, as you really are." (St Catherine of Sienna)

This is the journey of the soul: a journey of searching and finding, of hungering and of being satisfied only to hunger for more. Why can't we possess God here on earth? God in his mercy knows that the fullness of  our life is beyond our earthly existence. What we can know and experience of God in this life is merely a glimpse of the fullness of who he is. As St. Paul came to understand: "At present we see indistinctly, as in a mirror, but then face to face. At present I know partially; then I shall know fully, as I am fully known." (1 Cor 13:12) 

It is so easy for us to settle for the bird at hand than to push forward towards the flock of birds just beyond our immediate reach. God creates this hunger for him, so that we will not be satisfied with a temporary fix, like the addictive person, but seek what will satisfy us completely. God is the beginning and end of our life. Until we are with him completely, we will always be incomplete. Continue the journey. In the words of St. Paul: "It is not that I have already taken hold of it or have already attained perfect maturity, but I continue my pursuit in hope that I may possess it, since I have indeed been taken possession of by Christ [Jesus].Brothers, I for my part do not consider myself to have taken possession. Just one thing: forgetting what lies behind but straining forward to what lies ahead, I continue my pursuit toward the goal, the prize of God’s upward calling, in Christ Jesus." (Philippians 3:12-14)
