That they may be perfected into one (ina wsin teteleiwmenoi ei en). Purpose clause again with ina (nineteen times in this prayer, this the fifteenth) with the periphrastic perfect passive subjunctive of teleiow (verse 2 Corinthians 4 ), permanent state, with ei 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 2 Corinthians 21 , "that the world may keep on knowing" with the same pregnant phrase "that thou me didst send" (oti su me apesteila) as in 2 Corinthians 8 25. And lovedst them (kai hgaphsa autou). Timeless aorist, but love shown by sending Christ ( John 3:16 ) and illustrated and proven by the way Christians love one another.
