Atheism does not provide answers to Christianity as they do not believe in Christ, or his Father. It is also true that because they have not been converted by the testimony of the Holy Ghost that they cannot absolutely denounce the existence of God. The simply do not know. They cannot see what I see.
I understand completely the point you are making, however, the life of the atheist is based on what they believe to be true. They cannot know any different. They are more to be pitied then scorned. Their lives consist of three score and ten years, approximately, and then nothing. All that loving, caring, acquiring of knowledge and building of relationships all gone in the blink of an eye. I cannot think of anything more depressing. We should pity them for not having what we have got, and even worse then that, not wanting it either. When I die I will either continue to exist in Spirit, which I believe, or I will not exist at all. Either way I am in a win, win situation. If there is nothing then I will not care, I will be dead. If their is something then my bets have been edged and my efforts of being a morally accountable human being have not been in vain. The Atheist is in a lose, lose situation. If life continues then he will be in serious trouble. What does the astute intellectual do. Surely the wise choice is blatantly obvious, especially as God said that if you do as he commands then you will receive the testimony of the Holy Ghost. It is a promise. Surely if you have your head screwed on you would at the very least try, but people hate too change, to put in the effort, especially the rich.
