Mark 9:1Then Jesus said to them, “Truly I tell you, THERE ARE SOME STANDING HERE WHO WILL NOT TASTE DEATH UNTIL THEY SEE THE KINGDOM OF GOD ARRIVE WITH POWER.”
Who was He talking to? (I answer below)
I am not usually too big on commentaries, however will read them from time to time through Bible hub, as further insight and confirmation to what the Spirit has shown me. In such, I am in agreement with Ellicott’s Commentary for English Readers, from Matthew 16:28, (which is a cross reference to Mark 9:1):
“The solution of the problem is to be found in the great prophecy of Matthew 24. In a sense which was real, though partial, the judgment which fell upon the Jewish Church, the destruction of the Holy City and the Temple, the onward march of the Church of Christ, was as the coming of the Son of Man in His kingdom. His people felt that He was not far off from every one of them. He had come to them in “spirit and in power,” and that advent was at once the earnest and the foreshadowing of the “great far-off event,” the day and hour of which were hidden from the angels of God, and even from the Son of Man Himself (Mark 13:32). The words find their parallel in those that declared that “This generation shall not pass away till all be fulfilled” (Matthew 24:34).”
Yeshua/Jesus told His disciples this, and told them in their generation. That was the first century.
