Jesus’ claims here don’t seem all that straight forward to me. To claim as he is shown here: Whoever believes in me believes not in me but in him who sent me. And whoever sees me sees him who sent me. is not to point the finger away from himself and towards God but to point to himself and say — look here if you want to find God. In the religious context of his day — surely that was a call for absolute obedience to him.
And he doesn’t lay down the rules and regs here — yes he will later. But this is not about — do these things and you’ll be in God’s good books. There isn’t a list of instructions. Procedures. Laws. Rules.
What counts is relationship. Jesus — at least here — calls us to a relational kind of spirituality. Reject me and reject life. Follow me and embrace life. We’ll work out the details later.
