'Eternal' in the Bible

But even if we, or an angel from heaven, should preach to you a gospel contrary to that which we [originally] preached to you, let him be condemned to destruction!

As we have said before, so I now say again, if anyone is preaching to you a gospel different from that which you received [from us], let him be condemned to destruction!

For all who depend on the Law [seeking justification and salvation by obedience to the Law and the observance of rituals] are under a curse; for it is written, “Cursed (condemned to destruction) is everyone who does not abide by all things written in the book of the law, so as to practice them.”

For the one who sows to his flesh [his sinful capacity, his worldliness, his disgraceful impulses] will reap from the flesh ruin and destruction, but the one who sows to the Spirit will from the Spirit reap eternal life.
