Most good people are continuing to become better. They would rightly assume that, left without belief in God, they will continue to improve. What they lose without belief in God is not the ability to become better, but the rate at which they can become better, and how much better they become. There is a saying that the best time to plant a tree is twenty years ago, and the second best time is today. Likewise, no matter where you stand in your life, considering the existence of God today will accelerate your journey towards greater happiness, strengthen you in challenging times to come, and help you acquire more light and truth than you had ever considered existed.
