Mark 8:34-38

34 Then calling to Him the crowd and also His disciples, He said to them, "If any one is desirous of following me, let him ignore self and take up his cross, and so be my follower.

35 For whoever is bent on securing his life will lose it, but he who loses his life for my sake, and for the sake of the Good News, will secure it.

36 Why, what does it benefit a man to gain the whole world and forfeit his life?

37 For what could a man give to buy back his life?

38 Every one, however, who has been ashamed of me and of my teachings in this faithless and sinful age, of him the Son of Man also will be ashamed when He comes in His Father's glory with the holy angels."
