Hard Sayings of Christ

We stress God's grace and forgiveness, His mercy.  But, here it is, Peter desired to protect the Lord...

"And Peter took him aside and began to rebuke him, saying, "Far be it from you, Lord! This shall never happen to you."  Matthew 16:22

and the Lord came back with...

"But he turned and said to Peter, "Get behind me, Satan! You are a hindrance to me. For you are not setting your mind on the things of God, but on the things of man." Then Jesus told his disciples, "If anyone would come after me, let him deny himself and take up his cross and follow me.  For whoever would save his life will lose it, but whoever loses his life for my sake will find it. For what will it profit a man if he gains the whole world and forfeits his soul? Or what shall a man give in return for his soul?  For the Son of Man is going to come with his angels in the glory of his Father, and then he will repay each person according to what he has done."  -Matthew 16:23-27

These are hard sayings.  Peter wished for Jesus to be safe and established.  We are told to put the health of our soul first.
