As you quote, I consider myself (imperfectly) one with Jesus, but that does not make me equal at present with Jesus. Jesus has been raised from the dead and has been given an incorruptible body. The same body is assured to us, but whilst I do not have the same body as Jesus, I cannot say I am the same as Jesus. We are exhorted to have the mind of Christ and with the mind of Christ, then we should be at one with him. Jesus in saying he was one with the Father, was not making himself equal to God. I can never make myself equal to God. In the kingdom the only thing equal with God will be life eternal. From that point onwards those who are raised to be in the kingdom will live for ever and time will become meaningless.
