The first quality to be called and disciplined is Simon, or the attribute of hearing.
This faculty, when lifted to the level of a disciple, permits only such impressions to reach consciousness as those which his hearing has commanded him to let enter. No matter what the wisdom of man might suggest or the evidence of his senses convey, if such suggestions and ideas are not in keeping with that which he hears, he remains unmoved.
This one has been instructed by his Lord and made to understand that every suggestion he permits to pass his gate will, on reaching his Lord and Master (his consciousness), leave its impression there, which impression must in time become an expression.
The instruction to Simon is that he should permit only dignified and honorable visitors or impressions to enter the house (consciousness) of his Lord. No mistake can be covered up or hidden from his Master, for every expression of life tells his Lord whom he consciously or unconsciously entertained.
When Simon, by his works, proves himself to be a true and faithful disciple, then he receives the surname of Peter, or the rock, the unmoved disciple, the one who cannot be bribed or coerced by any visitor. He is called by his Lord Simon Peter, the one who faithfully hears the commands of his Lord and besides which commands he hears not.
It is this Simon Peter who discovers the I AM to be Christ, and for his discovery is given the keys to heaven, and is made the foundation stone upon which the Temple of God rests.
Buildings must have firm foundations and only the disciplined hearing can, on learning that the I AM is Christ, remain firm and unmoved in the knowledge that I AM Christ and beside ME there is no savior.
