Spiritually, I've heard all there is to hear on the matter. Often people think that their unhappy marriage is something that they'll just have to grin and bear until their partner changes. You won't know where you're going until you die and arrive there. All their life they live in fear of death and the unknown. And if He is the God who created me, then I must be answerable to Him.
Contemplation is the second stage of repentance and change.
Here you allow yourself to begin thinking in areas that you never thought in before. Is it possible that there is a degree and quality of joy and peace that is beyond anything you have imagined to be possible. Think of the immense change the Athenians were up against. The Stoics said that at death the soul would be burned and absorbed into God. Paul's talk of a resurrection from the dead was utter foolishness to them.
