And there were some standing there who did see Jesus/the Son of Man in His kingdom…
Now after six days Jesus took Peter, James, and John his brother, led them up on a high mountain by themselves; 2 and He was transfigured before them. His face shone like the sun, and His clothes became as white as the light. 3 And behold, Moses and Elijah appeared to them, talking with Him.
Matthew 17:1-3
I don’t think the verse below is in reference to the return of Christ.
When you are persecuted in one place, flee to another. Truly I tell you, you will not finish going through the towns of Israel before the Son of Man comes…
Matthew 10:23
“Another alternative is to take the promise literally and immediately and to interpret the phrase “before the Son of Man comes” as a reference to the fact that Jesus rejoined the disciples after their mission. This view may be supported by several facts.
First, the phrase “before the Son of Man comes” is never used by Matthew to describe the Second Coming. Second, it fits with a literal understanding of the first part of the verse.
The disciples went literally and immediately into “the cities of Israel” to preach, and Jesus literally and immediately rejoined them after their itinerant ministry. Third, there is no indication here or anywhere else that the disciples believed that Jesus was going to go to heaven while they were gone on their preaching tour. This certainly would have startled them (cf.
John 14:1–5). Furthermore, He had already told them that He had to die and rise from the dead (
John 2:19–22) before He could go to heaven and return.”
Is there a Bible contradiction in Matthew 10:23? Here’s the solution from When Critics Ask by Geisler and Howe; used by permission.
