What is the connection with the previous verse? It is that even though such faith exists in a believer and even though they are able to do such great things through faith, and remarkable things, they should still see themselves as servants, serving their master while they are on earth. Although Christ makes himself the servant of his disciples in another place, it is still true that a proper relation to him in this world makes us his servants.
It is true that believers have been adopted into God’s family, and given a privilege which cannot be measured, and which makes them more than servants. But while we are in the world, it is not good for us to forget that we are servants. Remembering that gives us a proper respect and reverence for our Lord, which would harm us greatly if it were not maintained. All the Lord’s love for us does not mean that he will allow this right relation to us to slip. Just as the servant is always on duty, and can only attend to himself when he has completed his day’s work for his master, so the believer is in this life constantly on duty and must never forget his duties to his heavenly Master. This is not due to the Master’s unwillingness to serve; Christ is indeed ‘meek and lowly of heart’. There is a wonderful promise in another place in which Christ tells us that in heaven there will be a transformation in this relationship. He says, ‘Blessed are those servants, whom the lord when he cometh shall find watching: verily I say unto you, that he shall gird himself, and make them to sit down to meat, and will come forth and serve them’ (Luke 12:37). In the life to come Christ will reward us in ways that we cannot now imagine, but in this life it is for our good that we continue to see ourselves as servants, because of our tendency to be elevated in our minds.
