Mark 8:35-38

For whoever wishes to save his life [in this world] will [eventually] lose it [through death], but whoever loses his life [in this world] for My sake and the gospel’s will save it [from the consequences of sin and separation from God]. [Matt 10:39; Luke 17:33; John 12:25] For what does it benefit a man to gain the whole world [with all its pleasures], and forfeit his soul? For what will a man give in exchange for his soul and eternal life [in God’s kingdom]? For whoever is ashamed [here and now] of Me and My words in this adulterous and sinful generation, the Son of Man will also be ashamed of him when He comes in the glory of His Father with the holy angels.”
