Love never ends. But as for prophecies, they will come to an end; as for tongues, they will cease; as for knowledge, it will come to an end. (1 Cor 13:8)
“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
