He spoke any and all languages necessary to accomplish His mission. If you went back in a time machine, He could break off a discussion in Greek in which He was translating Hebrew that Romans misunderstood in Latin, in order to wink at you and say something in Ebonics to correct your HTML code without breaking a sweat.
What part of “infinity” is not clear? LOL!
That is, of course true...however, I don't think that He cheated and actually did live the life that He chose. He was certainly free to wait until the 21st century to show up but He didn't...He could have stopped the crucifixation with a wave of His hand but He chose to go through with it. We are probably not qualified to judge how and why He chose to redeem mankind....but we can certainly be grateful that He did....eternity lasts a long time!!
