My grace is sufficient for you, for power is made perfect in weakness.” So, I will boast all the more gladly of my weaknesses, so that the power of Christ may dwell in me. (2 Cor 12:9)
“Do you realize what I have done for you? You call me ‘teacher’ and ‘master,’ and rightly so, for indeed I am. If I, therefore, the master and teacher, have washed your feet, you ought to wash one another’s feet. John 13:12–15
