Sometimes Scriptures have to be understood from an overall context. When Jesus taught of plucking out the eye or cutting off a hand to keep the eye or the hand from sinning causing you to be condemned to eternal torments, it is reasonably understood that this has to be more carefully analyzed. If that were to happen, it would be better to enter Heaven without an eye or hand than to be cast into Hell. However, no one is perfect, and all would be condemned except for the saving blood of Jesus. So, certainly, if plucking the eye or cutting off the hand should be necessary to enter Heaven, then it would be better to do so, but it certainly is not necessary. Jesus stressed the importance of avoiding sin, but He died to remove the sting of death.
Often much can be said in even one verse. Sometimes, even when the verse is understood, more understanding is gained from other related verses. Sometimes a verse is better understood by finding other verses that teach more in relation to that teaching.
Mark 8:34 And when he had called the people (multitude) unto him with his disciples also, he said unto them, Whosoever come after me, let him deny himself, and take up his cross (stake), and follow me. 35 For whosoever will (willeth) to save his life (soul) shall lose it; but whosoever shall lose his life (soul) for my sake and the gospel's (evangelism's), the (this) same shall save it. 36 For what shall it profit benefit a man (human), if (whenever) he shall gain the whole world (cosmos), and lose his own soul? 37 Or what shall a man (human) give in exchange for his soul?
38 Whosoever therefore (indeed) shall be ashamed (shame) of me and of my words in this adulterous and sinful generation; of him also shall the Son of man be ashamed (humanity shame), when he cometh in the glory of his Father with the holy angels. (ERRB)
Now losing one’s life to save his life may sound strange, but the idea is that letting go of your concerns for this world in favor of taking up your concern for Christ’s Kingdom is what is meant. If we truly accept Christ into our hearts, then this life (which at best is short-lived) is of little consequence in comparison to eternal life in a place Jesus is preparing for those who accept Him. Now compare this though with Jesus statement that we were not to store up treasures in this life, but to store up treasures for Heaven (Matthew 6: 19- 21). Considering this world as more important than the next world is equivalent to denying the truth of Christ’s teaching, so we should strive to do what is right to store up treasures in Heaven, as opposed to doing what seems right in this world and storing up our treasures here. This is also illustrated in Jesus’ teaching the rich man to sell what he had and give to the poor and he would have treasure in Heaven. His treasure here would be short-lived in his own hands, but used to help the needy to meet their needs would accumulate treasure for the rich man in Heaven, where his treasures would be more valuable and count for eternity. So truly believing in Jesus becomes a question of what do you consider more important, being what you want to be in this world, or becoming what Christ wants you to become. Referring back to the Matthew passage cited above, it says that where your treasure is, there will your heart be. So do you consider your real treasure in this world, or is the hope of Heaven where your real treasure is? Also compare to the story of the rich man and Lazarus. Abraham told the rich man that he had received his good things (treasures) in this world and now since he had no good things, treasures, above, he was now in torments (Luke 16: 25).
So if we truly trust in Jesus, and we seek a treasure in Heaven, we should (Verse 38 above) be ashamed of this adulterous and sinful generation (from Greek- genea- age, generation, nation, time (in short- this world we’re now in). Seeing that, we should not ‘treasure treasures’ in this world, but glory in Christ (as opposed to being ashamed of Christ) as told in Verse 38 above.
Mark 16:15 And he said unto them, Go ye into all the world (cosmos), and preach the gospel (evangelism) to every creature (all creation). 16 He that believeth (trusteth) and is baptized shall be saved; but (and) he that believeth not (distrusteth) shall be damned (condemned). (ERRB)
So if we remain unashamed of the gospel of Christ (Mark 8: 38; Romans 1: 16; Romans 5: 5; 2nd Timothy 1: 12) then we should be proud to tell others of what He has done for us. There will be those who will believe. Those who do not believe will be condemned.
2nd Timothy 1:12 For the which cause I also suffer these things: nevertheless (yet) I am not ashamed: for I know whom I have believed (trusted), and am persuaded (convinced) that he is able to keep (guard) that which I have committed (surrendered unto him) against (unto) that day. (ERRB)
