@CarsonWeitnauer I really struggle with this quote. Jesus was Master and King who came in the form of a servant, but today He reigns on high and will one day put all nations under His feet. He can relate to slaves, but He only spent a very brief time as a slave and then only by choice. He could have called down a legion of angels if He wanted to do so.
For me personally, it is much easier to orient myself in relation to Jesus Himself. Jesus set an example by washing the disciples’ feet, humbling Himself to the point of death on a cross and in pointing out in Luke that we are servants of God. Even after we have done all that we should, there is no room for a servant to boast.
Luke 17:10 - So you also, when you have done everything you were told to do, should say, 'We are unworthy servants; we have only done our duty.
John 13:14 - Now that I, your Lord and Teacher, have washed your feet, you also should wash one another’s feet.
So, in that sense, it is much easier for me to say with Paul that I am a ‘slave of Christ’ or ‘doulos’ and that I ought to imitate my Master. The idea of a ‘slave of the slaves of a slave’ simply does not capture the full picture for me.
