"For I have given you an example..."

When he had washed their feet and put on his outer garments and resumed his place, he said to them, “Do you understand what I have done to you? You call me Teacher and Lord, and you are right, for so I am. If I then, your Lord and Teacher, have washed your feet, you also ought to wash one another's feet. For I have given you an example, that you also should do just as I have done to you. Truly, truly, I say to you, a servant is not greater than his master, nor is a messenger greater than the one who sent him. If you know these things, blessed are you if you do them. 

-John 13:12-17

It is a great act of eternal love when Christ once for all absolves the sinner, and puts him into the family of God; but what condescending patience there is when the Saviour with much long-suffering bears the oft recurring follies of his wayward disciple; day by day, and hour by hour, washing away the multiplied transgressions of his erring but yet beloved child!....While we find comfort and peace in our Lord’s daily cleansing, its legitimate influence upon us will be to increase our watchfulness, and quicken our desire for holiness. Is it so? -CH Spurgeon
