βNeither pray I for these alone, but for them also which shall believeΒ on Me through their wordβ (John 17:20).
Most Bible commentaries maintain that the Lord was talking aboutΒ you and me, and all of the other members of the Body of Christ who hadΒ not yet believed on Him at that time. The problem with this view isΒ that you and I didnβt believe on Christ through the words of the twelveΒ apostles. We believed on Him through the words of the Apostle Paul!Β Paul is the only biblical writer who presents salvation by grace throughΒ faith in the blood of the Lord Jesus Christ (Rom. 3:25). If someoneΒ introduced you to Christ using the words of the twelve apostles, theyΒ had to read Paulβs gospel into their words, for he is the only biblicalΒ writer to preach the death, burial, and resurrection of Christ as theΒ gospel that must be believed in order to be saved (I Cor. 15:1-4).
So who were those who were saved through the word of the apostles?Β Well, the twelve preached their word at Pentecost, which tells us thatΒ those who believed through their word were all Jews, for they wereΒ the only people that Peter addressed on that day (Acts 2:14,22,36). SoΒ in praying for βthem also which shall believe through their word,β theΒ Lord was praying for future Jewish believers. Of course, this meansΒ that He had only Jewish believers in mind when He went on to prayΒ for these future saints.
βThat they all may be oneβ¦that the world may believe that ThouΒ hast sent Meβ (John 17:21).
Here again, the commentaries all contend that the Lord was talkingΒ about us. After all, didnβt Paul say of Christ, βHe is our peace, whoΒ hath made both oneβ (Eph. 2:14), speaking of how Jews and GentilesΒ were all βbaptized into one bodyβ (I Cor. 12:13). The commentariesΒ insist that this is what the Lord had in mind when He prayed βthatΒ they all may be one.β
But weβve already seen that this couldnβt be what the Lord hadΒ in mind, since those who believed on Him through the word of theΒ apostles were all Jews. So why was He praying that the Jews mightΒ be made one?
Well, if you know your Bible, you know that there came a time inΒ Israelβs history when the ten northern tribes broke away from the twoΒ southern tribes and formed their own kingdom (I Kings 12). WhileΒ God allowed this, He had no intention of letting His people be dividedΒ forever! To illustrate this, God instructed Ezekiel to take a stick andΒ write βIsraelβ on it to represent the ten northern tribes, and then to takeΒ another stick and write βJudahβ on it to represent the two southernΒ tribes, then to join them together and βmake them one stickβ (Ezek.Β 37:15-19). He was told to do all this to illustrate Godβs plan to takeΒ Israel and Judah and βmake them one nationβ (Ezek.Β 37:22). This, then, isΒ the oneness for which the Lord prayed in our text.
Was His prayer answered? You know it was! At Pentecost, βthereΒ were dwelling at Jerusalem Jewsβ¦out of every nation under heavenβΒ (Acts 2:5). βAnd all that believedβ¦were togetherβ¦continuing dailyΒ with one accordβ¦withβ¦singleness of heartβ (Acts 2:41-46).
Of course, the Lord had a purpose in mind for praying for the reunionΒ of Israelβs two houses. It was, as He said, βthat the world mayΒ believe that Thou hast sent Meβ; and when the reuniting of IsraelβsΒ two houses continues in the millennial kingdom, their oneness willΒ cause the world to believe on Christ.
Do you think this will work today? That is, when the world sees theΒ oneness that we have in Christ, do you think maybe they might want inΒ on it? I know for sure that it works the other way! When we bite andΒ devour one another, the world about us finds this most UNattractive.Β Brethren, do you know who does the most to keep people from believingΒ on Christ? It is not murderers, rapists, and thieves; nothing thatΒ men like that do keeps men from believing. No, it is Christians whoΒ canβt get along with one another, and who present a poor testimonyΒ to the world in other ways, that keep men from believing on Christ.Β Why not determine right now that as a Christian you are going toΒ βwalk worthy of this callingβ¦that the name of our Lord Jesus ChristΒ may be glorified in youβ (II Thes. 1:11,12). source
