The Secret of Unity
In John 13, Jesus took a towel and a basin and washed the feet of his disciples.
“If I then, your Lord and Teacher, have washed your feet, you also ought to wash one another’s feet” (John 13:14). After he had washed their feet, he asked them, “Do you know what I’ve just done for you?” In other words, “Do you understand the spiritual significance of foot washing?”
I believe when Jesus washed the feet of the disciples, he was teaching a profound lesson on how to obtain unity of fellowship within the Body of Christ.
