When you look for a "doctor father" to guide your Ph.D. program, you'll try to get to know everything you can about him. Ideally you should have at least one interview with him in person. But for a well-rounded picture, you'll need to spend time talking with his associates and former students. This should give you a fairly balanced impression of who he is.
In trying to get to know Jesus Christ, the same method applies. You begin in the Gospels, reading what Jesus said about himself. A red letter edition of the Bible can be helpful here. In addition, you'll want to read what those who knew him best had to say. John's Gospel is a good example. He interpreted Jesus' life as only a close friend could.
Then there's Paul. Though he never met the earthly Jesus, his epistles are full of reflection and commentary. He knew the Savior well, and he wants us to get to know him as well as he does.
I'd give anything to able to talk to Jesus in person. But I know that won't happen until I see him face to face. Until then, I can still see him clearly through his word. So can you.
