Christians should live according to the Bible. Jesus was a great example and while many may follow after Paul, Peter, John, or another, we must realize that these men were only trying to follow Jesus Christ. To give scripture:
1 Be ye therefore followers of God, as dear children;
2 And walk in love, as Christ also hath loved us, and hath given himself for us an offering and a sacrifice to God for a sweetsmelling savour.
So to follow Christ is to follow God. Walk in love as Christ did. Of course, this subject is very detailed and this post alone cannot cover everything. Instead, this article is only meant as an introduction to the other articles. There are many other scriptures we will look into and find out what they say.
