John 17:21 Commentary - Garner-Howes Baptist Commentary
1) "That they all may be one;" (hina pantes hen osin) "in order that all may be (exist as) one," in unity, harmony, as one flock, united with one Lord, one faith, and one baptism, Eph 4:1-5; one in spirit, faith, doctrine, and practice.
2) "As thou, Father, art in me, and I in thee," (kathos su pater en emoi kago en soi) "And just as you, Father, exist in me and I exist in you," to give eternal life to those who believe, Joh 10:27-29; Joh 14:9. Truth, the word of truth, is the unifying element that affords cohesion, through the spirit, in building the house or church of Jesus Christ on earth, 1Ti 3:15; Eph 2:19-22.
3) "That they also may be one in us:" (hina kai autoi en hemin osin) "In order that they may also exist in us," Joh 10:30, continually in our will and work, as I have in yours, Joh 6:38; Joh 4:34; Joh 17:4-5.
4) "That the world may believe that thou hast sent me." (hina ho kosmos pisteue hoti su me apesteilas) "In order that the world may believe that you did send me," by the life they live, in following me, and the way they let their light shine, Luk 9:23; Mat 5:15-16; Joh 13:34-35.
