Draw closer and we begin to see each others' major flaws, wrongful passions, and besetting sins. After this, getting to know Jesus could have only been a combination of delight and fear for Peter.

And when he had spoken this, He saith unto him, Follow Me. No doubt Jesus spoke these words with Jacob's vision of a ladder with ascending and descending angels, recorded in Genesis 28, in mind. Filled with the consciousness of His Own Messianic calling, being at or near the very place where Jacob dreamed, He proclaims Himself the fulfillment of the covenant, the true ladder, the bridging of the gap between heaven and earth. Angels are the messengers of God, serving the heirs of salvation, and it is upon the person and work of Jesus that they move. At Jesus' command, the angels of God encamp about the righteous, unseen and mighty protectors.
