John Chapter 17, Verse 21
From BibleWiki
21: ινα παντες εν ωσιν καθως συ πατερ εν εμοι καγω εν σοι ινα και αυτοι εν ημιν εν ωσιν ινα ο κοσμος πιστευση οτι συ με απεστειλας
21: That they all may be one; as thou, Father, art in me, and I in
thee, that they also may be one in us: that the world may
believe that thou hast sent me.
21: That they all may be one, as thou, Father, in me, and I in thee;
that they also may be one in us: that the world may believe that thou
hast sent me.
All may be one. May be united as brethren. Christians are all redeemed by the same blood, and are going to the same heaven. They have the same wants, the same enemies, the same joys. Though they are divided into different denominations, yet they will meet at last in the same abodes of glory. Hence they should feel that they belong to the same family, and are children of the same God and Father. There are no ties so tender as those which bind us in the gospel. There is no friendship so pure and enduring as that which results from having the same attachment to the Lord Jesus. Hence Christians, in the New Testament, are represented as being indissolubly united -- parts of the same body, and members of the same family, Acts 4:32ff. 1Cor 12:4ff Eph 2:20ff Rom 12:5.
On the ground of this union they are exhorted to love one another, to bear one another's burdens, and to study the things that make for peace, and things wherewith one may edify another, Eph 4:3 Rom 12:5ff.
As thou, Father, art in me. See Jn 14:10 This does not affirm that the union between Christians should be in all respects like that between the Father and the Son, but only in the points in which they are capable of being compared. It is not the union of nature which is referred to, but the union of plan, of counsel, of purpose -- seeking the same objects, and manifesting attachment to the same things, and a desire to promote the same ends.
That they also may be one in us. To be in God and in Christ is to be united to God and Christ. The expression is common in the New Testament. The phrase here used denotes a union among all Christians founded on and resulting from a union to the same God and Saviour.
That the world may believe, &c. That the world, so full of animosities and fightings, may see the power of Christian principle in overcoming the sources of contention and producing love, and may thus see that a religion that could produce this must be from heaven. See "Jn 13:34".
This was done. Such was the attachment of the early Christians to each other, that a heathen was constrained to say, "See how these Christians love one another!"
