First of all you have to love the Lord Jesus Christ completely.  You have to really believe in the cause: that he is the Son of God, and he died for your sins on the Cross. It is important to get a Water Baptism done with a preacher. This is basically to be "born again in the faith" or beginning a new life with the Lord Jesus Christ. Buy a Bible and read it often. This is easily the Greatest Book ever written. It includes lessons, adventures, heroes, ideals, trials, tribulations, and some great advice on how to be the best person you can possibly be. You should also try to live your life every day (not just when it's convenient) following the 10 Commandments, and certain other rules. The 10 Commandments can be found in the Book of Exodus 20:3. Some of the other rules are: "Treat others how you want to be treated."and "Love thy neighbor as thyself".  These are important folks, because they helps educate the christian individual to conduct themselves in a christian/ holy manner and they reinforce some of the fundamental christian ideals such as: love, generosity, kindness, peace, honesty, ethics, character, and friendship. Go to church. The church is a very special place. Here you will find lessons, sermons, singing, worship, praise and have the opportunity to interact with, and meet some amazing christian people! Churches are also involved sometimes with feeding the poor, clothing the homeless, helping the sick, and charity work as well. These activities can be very rewarding, because you are doing something great for someone who often times really needs your help. It also helps to watch christian programming on TV, and listen to christian music as well. In closing I would like to say that christianity is love. Love for the Lord Jesus Christ, and for the people of the world as well. Thank you.
