Luke 9:26-30

Luke 9:26 (KJB)
For whosoever shall be ashamed of me and of my words, of him shall the Son of man be ashamed, when he shall come in his own glory, and in his Father's, and of the holy angels.

Jesus is stating that a person must be fully sold out to the Gospel by means of having it permeate every facet of their life. In this verse we are reading that one must be vocal for the Lord Jesus Christ being a testimony for Him in this adulterous and evil generation which is speaking about the entire time sinful man is on this earth. A person claims to be a Christian and then does absolutely nothing with their life in the realm of being a witness for the Lord Jesus, then they are showing that they are ashamed of the Lord Jesus and His words. For some Christians, it is easier to quote theologians than to quote Jesus Himself because they fear the ridicule of the world. If that is the case with any person who claims to be a Christian, then Jesus will show that He is ashamed of them because so many Christians in this world have become martyrs for the Lord. This person will be an outcast and Jesus will not claim him as one of His own. Jesus suffered and died for the true Christian and we need to proclaim that and not keep it to ourselves. (2 Tim 1:8 KJV) Be not thou therefore ashamed of the testimony of our Lord, nor of me his prisoner: but be thou partaker of the afflictions of the gospel according to the power of God; The Apostle Paul wrote to Timothy that he should not be ashamed of the testimony of the Lord and of him who was in prison. Those who would show shame for the Gospel are those who do not want to take the persecution which comes with it. Normally these are the unbelievers who only affirm the Gospel when it is convenient or have no chance of persecution. Those who are ashamed of the Lord are those who are unbelievers who claim to be Christians. Some Christians may be timid but that does not mean they are unbelievers.

Luke 9:27 (KJB)
But I tell you of a truth, there be some standing here, which shall not taste of death, till they see the kingdom of God.

Then the Lord Jesus makes a statement that some of the disciples who were standing there with Him will not die until they see Him coming in His kingdom. This is speaking of the upcoming time on the Mount of Transfiguration because if you notice the words “see” the kingdom of God. Some have interpreted this to be the outpouring of the Holy Spirit on Pentecost and the destruction of Jerusalem in 70 A.D. but this could not be because it is pointing to the Mount of Transfiguration. They will get a glimpse of the glory of Heaven.

Luke 9:28 (KJB)
And it came to pass about an eight days after these sayings, he took Peter and John and James, and went up into a mountain to pray.

Traditionally speaking this high mountain, Mount Tabor, was the site of the transfiguration of Jesus but there is nothing to support it. It is more likely that it was Mount Meron (Jebel Jermuk) which was 12 miles (19 km) northwest of Capernaum which is the area where they were at. Instead of Jesus taking all the disciples with Him, He had only taken Peter, James, and John which is sometimes called Jesus’ inner circle. This was not just a hill but a high mountain. Then Jesus left them a little distance away and was transfigured from an ordinary human being into what He would have looked like in all His glory in Heaven.

Luke 9:29 (KJB)
And as he prayed, the fashion of his countenance was altered, and his raiment was white and glistering.

Then Jesus left them a little distance away and was transfigured from an ordinary human being into what He would have looked like in all His glory in Heaven. His face was shining as the sun because of the glory beaming from it and His clothes was as bright as the light. Peter, James, and John had to be qualified to see this or else they would have been consumed by the glory. The glory which Jesus exuded was not coming at Him but rather it was emanating out from Him. For those few moments, He was endowed with His glorified, heavenly body. This event could have happened at night since Luke records that Peter, James, and John were heavy with sleep. (Luke 9:32 KJV) But Peter and they that were with him were heavy with sleep: and when they were awake, they saw his glory, and the two men that stood with him.

Luke 9:30 (KJB)
And, behold, there talked with him two men, which were Moses and Elias:

(Mal 4:4-5 KJV) Remember ye the law of Moses my servant, which I commanded unto him in Horeb for all Israel, with the statutes and judgments. {5} Behold, I will send you Elijah the prophet before the coming of the great and dreadful day of the LORD: Malachi records both the names of Moses and Elijah. It is not specifically known what they spoke about but it is believed they spoke about Jesus fulfilling all the Scriptures in the law (Moses) and the prophets (Elijah) who prophesied His coming and death and resurrection. It was a heavenly witness of the ministry of the Lord Jesus Christ.
