Whoever wants to be my disciple must deny themselves and take up their cross daily and follow me

Luke 9:18-43a

Jesus asked his disciples, “Who do the crowds say I am?

“But what about you?” he asked. “Who do you say I am?” Peter answered, “God’s Messiah.” Jesus strictly warned them not to tell this to anyone. And he said, “The Son of Man must suffer many things and be rejected by the elders, the chief priests and the teachers of the law, and he must be killed and on the third day be raised to life.” (First time)

Then he said to them all: “Whoever wants to be my disciple must deny themselves and take up their cross daily and follow me.

About eight days after Jesus said this, he took Peter, John and James with him and went up onto a mountain to pray.

A voice came from the cloud, saying, “This is my Son, whom I have chosen; listen to him.” When the voice had spoken, they found that Jesus was alone. The disciples kept this to themselves and did not tell anyone at that time what they had seen.

“You unbelieving and perverse generation,” Jesus replied, “how long shall I stay with you and put up with you? Bring your son here.”

But Jesus rebuked the impure spirit, healed the boy and gave him back to his father. And they were all amazed at the greatness of God.

(Second time): “Listen carefully to what I am about to tell you: The Son of Man is going to be delivered into the hands of men.” But they did not understand what this meant. It was hidden from them, so that they did not grasp it, and they were afraid to ask him about it.

Jesus refused to call fire down from heaven to destroy them, the Samaritan Opposition. 
Why?

Who do you say Jesus is? Same as Peter,  “God’s Messiah.”

Why did Jesus bring Peter, John, and James to the mountain and see Jesus' transfiguration? More missions will be given to them.

The disciples could not drive the demon out of the child, because of the faith, unbelieving and perverse generation. But the Father knew and believed Jesus could make it. No faith means the power of the Lord, perverse means the words of the Lord. Jesus feels sad about his disciple's drive daemon by their own mind and way.

Jesus refused to kill the Samaritan Opposition because the time of the Lord has not come yet. The Lord allows them to repent through Jesus Christ.

How?

How do you give your life for God's sake? Do my best, Dear Lord, please give me the ability and strength to follow you.
