why

You don't need to believe in Christianity, Christianity is a fact.

only a christian or the devil will try to convince you of that.

If you mean, "why should you believe in the ideas of Christianity?", then you need to decide if those ideas are beneficial to you in some way. If they are, then go ahead and believe. The same could be said for virtually any belief system.

Because it's an option - if you are looking for a religion.

But investigage other spiritual guides.

You'd be surprised how little of the earth's population is Christian.

You should believe in Jesus. Don't make Him into a system that you can reject.
And probably that is exactly why you do. There is nothing personal, no God, no love, no redemption, no mercy, no forgiveness -- just a system you can argue about over a beer.

Jesus...and if you boast of not knowing what Jesus said about why you have another problem

This question shows you are a thinking person which is very good. For a fact because of the bad example of many who profess to be followers of Christ, many have a bad view of Christianity. But this is where the Bible can help clear up matters on what true Christianity is as opposed to false, and show you why it is very beneficial to become a true Christian.

At Matthew Chapter 7 and verses 21-23, Jesus made it clear that not everyone claiming to be his followers would actually be Christians. Please consider what he says there.

Also, Jesus demonstrated what true Christianity should relfect. A true love for God and for fellow humans as revealed at John 13:35. True Christianity also highlights how God's Kingdom will bring an end to the suffering and pain experienced by many and fix earthwide the problems that human governments are just simply unable to solve.

What God's Kingdom will accomplish:
1: Bring an end to all war: Psalm 46:9
2: All wicked to be removed: Psalm 37:9-11, 29; Matthew 5:5
3: Sickness and death done away with: Revelation 21:3, 4.

If you wouold like to know more there is a wonderful Christian website called Jw.org. There you will find a great deal more that shows why true Christianity is something you would really find beneficial and appealing.

You need first to know what it is you are asking your question about.
So go see what Christianity IS --- FIRST

Haven't been inside one for quite some time.. Generally it was
a fair socializing medium. The Sunday school part, that is.
