If Christianity is so good, why didn't the Christians keep it to themselves?

Cause they are desperate to conquer the world.

Main thing a Christian is to share is the good news about the gift of God. Which is Eternal Salvation through Jesus Christ our Lord. That's Good news! God's Love for you is better and more intense then any Love you will have for a spouse or any love for any human being on earth. To explain it, the Love God showed me had me on the floor wheeping in tears and hyperventilating. It's real. o yeah. And now is the time of Salvation. I will pray for you to experience His love! If one where to keep Christianity to themselves........well, you know.

And don't listen to the guy above. Bless his heart. Good does'nt out weigh the bad when you die. Why would Jesus had Died and rose again on the 3rd day then if we could obtain salvation with good works?

Ephesians 2:8

King James Version (KJV)

8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:

9 Not of works, lest any man should boast.

Hallo,keeping to ones self depicts greediness/selfishness hence since they are generous they share.

Because Jesus said go Make disciples in All nations so we want to spread to message so all of humanity can be saved and go to heaven.

Like love, Christianity is better when you share it.

Jesus wants us all to go out and tell you folks about Jesus! and to except Jesus into your heart the best way you can. and then Jesus will then live in your hearts.he said Jesus said "what up" ?!?

They didn't. Your ancestors were Christians. Did you not know that?

Because the only way to keep it is to give it away.

Unless you are assuming Christians are selfish, which wouldn't really be incorrect

You don't understand. What good is a way of thinking if you can't purport its benefits to someone else?

You will eat those words at your judgment,

when you realize what you passed up.
