17:31 judge the world. God, who created all men, must be the Judge of all men, and “the Judge of all the earth” will certainly “do right” (see Genesis 18:25). And since God both “created all things by Jesus Christ” (Ephesians 3:9), and has also “made peace through the blood of His cross, by Him to reconcile all things unto Himself” (Colossians 1:20), it is appropriate that “He shall judge” all things by Christ. See also John 5:22,27; Matthew 25:31-46.
17:31 raised him from the dead. Death has always been man’s greatest, and finally victorious enemy (I Corinthians 15:26), and only the Creator of life, the Judge who imposed the sentence of death because of sin (Genesis 3:17-19), can conquer death. The founders and leaders of all other religions and philosophies eventually die, but Jesus Christ is alive! His tomb is empty, and He has ascended in His resurrection body to the Father in heaven. His bodily resurrection, which can be shown to be the best-proved fact of Biblical history, is the certain assurance that He is the Creator and Judge of all.
