I deal with atheists all the time in my work as a chaplain. I have one man, dying of cancer that I visit weekly, and he is starting to get very down right now about the pain and complications in his life. He told me he is ready to die, as the cancer has spread, and there is no hope.
But he is also a very kind and placid person. Most people in his state would at least want to hear the reasons for the hope we have as Christians, but he has hardened his heart to the gospel. I just said to someone the other day, "How do people who do not believe in God weather these storms and death?"
I also have some wonderful Christian centenarions that I visit. One lady was failing fast and hanging onto God, as she lay bed ridden a few months ago. Yesterday I found her in the hall, in her wheelchair, exercising. She is blind, but has an incredible hope and faith in God, and it is a joy to be with her, and many of the very old Christians. That is my blessing!
We all suffer in this life, but I think the real difference is hope, when difficulty arises. I know God has used my suffering and pain to bring me closer to him, to change me radically, and to do ministry. I do pray for all those who do not know Christ. I still cannot understand how atheists do get through pain, suffering or trials and tribulations.
As for me, this verse is the life verse God gave me when my foot reconstruction failed, and I hold onto it each day when the pain is severe.
"Not only that, but we rejoice in our sufferings, knowing that suffering produces endurance, [SUP]4 [/SUP]and endurance produces character, and character produces hope, [SUP]5 [/SUP]and hope does not put us to shame, because God's love has been poured into our hearts through the Holy Spirit who has been given to us." Romans 5:3-5
