Why do some atheists become Christians?

Most times, Christian s become atheist.

A new belief, a reconciliation, faith, fear...

Why does anyone become a Christian? You see your condition before a Holy God, You can do doing to save yourself. God has in His mercy provided a way to be saved. Salvation is very simple, living it is hard.

A man who was an atheist was amazed to learn that the Bible does not teach that the wicked are tortured in a fiery hell. The Bible likens death to sleep. In the grave, we feel no pain; we are conscious of nothing at all. (Ecclesiastes 9:5, 10) The man also learned that those humans whom God judges to be incorrigibly wicked will remain in the grave forever. (Matthew 12:31, 32) The rest of the dead will be resurrected in God’s due time, with the prospect of obtaining everlasting life under Paradise conditions. (John 5:28, 29; 17:3) This explanation made sense. It harmonized with the Bible’s statement that “God is love.” (1 John 4:8) This sincere man continued his study of God’s Word and, in time, came to love the God of the Bible.

The ones I've personally seen... Peer pressure.  And they don't *really* become Christians.  They just say they are so people will stop pestering them.

OR ... They get in a relationship with someone who insists they have to share the same religion.  Again, they usually just say they are.

In fact, most "Christians" in America don't follow Biblical teachings completely - so it's not that difficult to "fake it".

I've seen them become believers after something happens they can't explain away. A loved one suddenly being healed or a near death experience. Even just a severe illness or depression. One just had a dream over and over after an aunt died. The same reason they don't believe for no real reason.

The same reason Christians or religious people turns atheists.

Different reasons that make them change their belief, actions,reasons,explanations, & experiences that makes them certain they have been away from what's truth (to them) so they start following their new truth belief.

People change over time. Our opinions do not stay the same. I remember when I was in high school, I was one of those "nice guys" who agreed with girls when they said women were always right. I grew up, though, (and hopefully those girls did, too) and now I know that women aren't always right. Women are human beings like the rest of us: We all think we're right.

A year ago, I believed religion causes war. Now, I know that religion never caused war; humans simply use religion as a means to justify going to war.

Somebody introduced them to religion - after they'd decided there were no gods, but without much research. Obviously, if a non-believer turns into a believer, they never really thought about it. I can't think of a situation where a believer finally learns enough to allow themselves to be atheist, and then go back.

Education made us atheists. It most certainly will not take us backwards.

Anthony Flew comes to mind.

Fortunately, this is a rare occurrence where one through many illogical turns, or just plain fear, loses rationality and goes to or returns to mindless superstition.

My friend  became a Christian and the reason why is, he decided to have a personal study of the bible and he learned that God wants people to enjoy life on earth and soon he will act to provide a better future for people in every land. He will relieve mankind of the causes of suffering.  Jeremiah 29:11 ,Isaiah 25:8, 33:24;

because they become saved.
