Criteria of a disciple of Jesus

Mark 8:27-38
Jesus asked his disciples "Who do you say I am?"
It is the first time Jesus told his followers that he will suffer death, and afterwards rise again.
Whoever wants to be my disciple must 1)deny themselves and 2)take up their cross and 3)follow me. --> 1)Give up all my own honor, property and time 2)endure the stress of environment and suffer the mock and difficult, even dangerous 3)follow what Jesus did, humble yourself.
For whoever wants to save their life will lose it, but whoever loses their life for me and for the gospel will save it.
What good is it for someone to gain the whole world, yet forfeit their soul? Or what can anyone give in exchange for their soul?  NO, it is nothing when lost soul.
If anyone is ashamed of me and my words in this adulterous and sinful generation, the Son of Man will be ashamed of them when he comes in his Father’s glory with the holy angels.
Why?
Jesus told them the real eternal life and how to get this eternal life, and the criteria of his disciple.
Follow Jesus is a mission not a easy journey, but the destination is honor and joy.
Ashamed of Jesus won't follow him, if follow Jesus do not afraid to be ashamed for Jesus is with us.
Our life in this world is short and temporary like a journey will end.
Lost life for Jesus and for gospel means follow Jesus and preach gospel even lost his life will gain eternal life in the heaven.
How?
Follow Jesus has to forsake all of my own and do what Jesus has done, to be his shape of behavior. Can I do it? I don't know, I will try to do it, Please give me faith and strength to follow you, O Lord.
