Mark 8:32-38 AMP

32 And He said this freely (frankly, plainly, and explicitly, making it unmistakable). And Peter took Him by the hand and led Him aside and then [facing Him] began to rebuke Him.

33 But turning around [His back to Peter] and seeing His disciples, He rebuked Peter, saying, Get behind Me, Satan! For you do not have a mind intent on promoting what God wills, but what pleases men [you are not on God's side, but that of men].

34 And Jesus called [to Him] the throng with His disciples and said to them, If anyone intends to come after Me, let him deny himself [forget, ignore, disown, and lose sight of himself and his own interests] and take up his cross, and [joining Me as a disciple and siding with My party] follow with Me [continually, cleaving steadfastly to Me].

35 For whoever wants to save his [higher, spiritual, eternal] life, will lose it [the lower, natural, temporal life which is lived only on earth]; and whoever gives up his life [which is lived only on earth] for My sake and the Gospel's will save it [his higher, spiritual life in the eternal kingdom of God].

36 For what does it profit a man to gain the whole world, and forfeit his life [in the eternal kingdom of God]?

37 For what can a man give as an exchange (a compensation, a ransom, in return) for his [blessed] life [in the eternal kingdom of God]?

38 For whoever is ashamed [here and now] of Me and My words in this adulterous (unfaithful) and [preeminently] sinful generation, of him will the Son of Man also be ashamed when He comes in the glory (splendor and majesty) of His Father with the holy angels.
