Who is Jesus to me? He has to first be Savior and LORD before He can be my Teacher. Anyone who only calls Him Teacher must be hopeless, because no pupil or disciple could really accomplish His teaching; not even the best ever student could accomplish his teaching. I need Jesus first to be Savior and LORD. I need first that very realization that I cannot accomplish even a portion of his teaching, because THEN I am 'poor and humble in spirit' enough to know my need for rescue from my undeserving and incapable condition.
Only then can I look with any confidence at His teaching for my life as His disciple and follower. Without His rescue I would only live in despair all the days of my life in comparison to the life he teaches me to live.
Ozzie Chambers wrote, "He came to make me what He teaches me I should be."
I am saved and controlled and covered by His Spirit in those places I wish I could do on my own but could never hope to accomplish on my own. If I begin with my poor and humble need, Jesus says, "You are blessed." (Matthew 5)
You will be happy if you begin with your humble view and realization that you could never accomplish the half of His teaching on your own if not for His Spirit and salvation within.
