Robertson's Word Pictures (NT)
That they may be perfected into one (ina wsin teteleiwmenoi eiv en). Purpose clause again with ina (nineteen times in this prayer, this the fifteenth) with the periphrastic perfect passive subjunctive of teleiow (verse John 17:4), permanent state, with eiv en (into one) as the goal and final result.
That the world may know (ina ginwskh). Present active subjunctive of ginwskw with ina like the present tense of pisteuw in verse John 17:21, "that the world may keep on knowing" with the same pregnant phrase "that thou me didst send" (oti su me apesteilav) as in John 17:8, John 17:25.
And lovedst them (kai hgaphsav autouv). Timeless aorist, but love shown by sending Christ (John 3:16) and illustrated and proven by the way Christians love one another.
