What a startling thing it is to realize that in John 13:15, the Lord Jesus Christ is commanding His disciples to treat one another in the same way that He has treated them. They are to do for one another the same things that He has done for them!
One of the first thoughts that comes into my mind when I think about this is, "Yeah, but He is supernatural--He is God Himself. How can I be expected to do for others what He has done for me?" Then the Holy Spirit reminds me that His Spirit is in me, to do through me what I cannot do myself.
The immediate context of this command is the washing of the disciples feet. But it would be unwise to limit this command to that act alone, since that act served as a symbol of the love and care that His disciples are to have for one another.
What has the Lord Jesus Christ done for His disciples, that they should also do for one another?
- He has loved them. “A new commandment I give to you, that you love one another: just as I have loved you, you also are to love one another.” (John 13:34 ESV)
- He has forgiven them and been kind to them “And be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ’s sake hath forgiven you.” (Eph 4:32 KJV)
- He has sacrificially supplied their needs according to His ability. “Hereby perceive we the love of God, because he laid down his life for us: and we ought to lay down our lives for the brethren. But whoso hath this world’s good, and seeth his brother have need, and shutteth up his bowels of compassion from him, how dwelleth the love of God in him? My little children, let us not love in word, neither in tongue; but in deed and in truth. And hereby we know that we are of the truth, and shall assure our hearts before him.” (1John 3:16-19 KJV)
“Truly, truly, I say to you, whoever receives the one I send receives me, and whoever receives me receives the one who sent me.”” (John 13:20 ESV)
There is no way to separate our relationship with Christ, from our relationship with His disciples. May the Lord help us to apply these truths in our relationships with each other!
