Who is Jesus? How do I learn more about him? How do I know the way he would want me to live?

Jesus is more than just a great teacher, He is everything.

There is a book of the Bible named Colossians which explains Jesus like this:

16 For in him all things were created: things in heaven and on earth, visible and invisible, whether thrones or powers or rulers or authorities; all things have been created through him and for him. 17 He is before all things, and in him all things hold together. 18 And he is the head of the body, the church; he is the beginning and the firstborn from among the dead, so that in everything he might have the supremacy. 19 For God was pleased to have all his fullness dwell in him, 20 and through him to reconcile to himself all things, whether things on earth or things in heaven, by making peace through his blood, shed on the cross.
-Colossians Chapter 1 Verses 16-20
