John 13:14 If I then, your Lord and Master, have washed your feet;
ye also ought to wash one another's feet. 13

Foot washing or the odinance of humility was designed to help prevent pride from rising within the church. If it was important enough that Christ [God] washed feet it is important enough that we should follow His footsteps and His direct command. We are all servants. The puting away of human pride is part of the process of sanctification.
1Pe 2:21 For even hereunto were ye called: because Christ also suffered for us, leaving us an
example, that ye should follow his steps:
1Jo 2:6 He that saith he abideth in him ought himself also so to walk, even as he walked.
Pro 29:23 A man's
pride shall bring him low: but honour shall uphold the humble in spirit.
1Jo 2:16 For all that is in the world, the lust of the flesh, and the lust of the eyes, and the
pride of life, is not of the Father, but is of the world.
