John Wesley on John 17:2

As thou hast given him power over all flesh - This answers to glorify thy Son. That he may give eternal life, &c. - This answers to that thy Son may glorify thee. To all whom thou hast given him - To all believers. This is a clear proof that Christ designed his sacrifice should avail for all: yea, that all flesh, every man, should partake of everlasting life. For as the Father had given him power over all flesh, so he gave himself a ransom for all.
