Most assuredly, I say to you, a servant is not greater than his master; nor is he who is sent greater than he who sent him. (John 13:16)
There is a difference between greater and better. Greater has to do with office while better has to do with character. Jesus said, “‘I am going to the Father,’ for My Father is greater than I.” If He would have said, “‘I am going to my Father,’ for My Father is better than I,” the whole of our theology would drastically be changed. The Father and the Son in essence are One. Nevertheless, while the Lord Jesus walked this earth He was subservient to His Father. The reason being was because of the office held. The Father reigned in heaven, the Son served on the earth. Therefore those who follow are not of a lesser value or significance, but of a lesser office. The employer is greater in office than the employee, but not better. Likewise the one sending is greater than the one sent—even if the one sent is of a higher character than the sender. As a matter of fact, an obedient servant is better than an insolent leader.
