And Jesus was saying to them, “Truly I say to you, there are some of those who are standing here who will not taste death until they see the kingdom of God after it has come with power.” Mark 9:1
Its often been debated about what Jesus was talking about here. Many conclude that Jesus was referring to the Transfiguration, because it happens typically right after this event. And I agree the transfiguration was a glimpse into the power and glory of Gods Kingdom to come. As we see Moses representing The Law and Elijah representing the Prophets come together under Jesus to be fulfilled
But when did we see the Kingdom of God come into power? We saw it on the cross, when Jesus defeated sin and death, Jesus fulfilled The Law, Jesus defeated Satan forever. The power of Gods Kingdom was displayed at Calvary.
As they were coming down from the mountain, He gave them orders not to relate to anyone what they had seen, until the Son of Man rose from the dead. Mark 9:9
Notice what Jesus says to Peter, James, and John after the Transfiguration. “Don’t tell anyone until after the Resurrection” Why? Because it was then the Kingdom of God has come into power here on Earth. Sin, Death, and Satan have all been defeated at the cross!
Therefore when Jesus had received the sour wine, He said, “It is finished!” And He bowed His head and gave up His spirit. John 19:30
When Jesus said “It Is Finished” he fulfilled his mission to save humanity. The Heavens and the Earth shook when the power of Gods Kingdom came to Earth through Jesus Christ Amen!
