21 From that time on Jesus began to show his disciples that he must go to Jerusalem and suffer many things at the hands of the elders, chief priests, and experts in the law, and be killed and on the third day be raised. 22 So Peter took him aside and began to rebuke him: “God forbid, Lord! This must not happen to you!” 23 But he turned and said to Peter, “Get behind me, Satan! You are a stumbling block to me because you are not setting your mind on God’s interests, but on man’s.” 24 Then Jesus said to his disciples, “If anyone wants to become my follower, he must deny himself, take up his cross, and follow me. 25 For whoever wants to save his life will lose it, but whoever loses his life because of me will find it. 26For what does it benefit a person if he gains the whole world but forfeits his life? Or what can a person give in exchange for his life?27 For the Son of Man will come with his angels in the glory of his Father, and then he will reward each person according to what he has done. 28 I tell you the truth, there are some standing here who will not experience death before they see the Son of Man coming in his kingdom.”

Pirkei Avot 2:1
1Rabbi Said: which is the straight path that a man should choose for himself? One which is an honor to the person adopting it, and [on account of which] honor [accrues] to him from others. And be careful with a light commandment as with a grave one, for you did know not the reward for the fulfillment of the commandments. Also, reckon the loss [that may be sustained through the fulfillment] of a commandment against the reward [accruing] thereby, and the gain [that may be obtained through the committing] of a transgression against the loss [entailed] thereby. Apply your mind to three things and you will not come into the clutches of sin: Know what there is above you: an eye that sees, an ear that hears, and all your deeds are written in a book.
