Romans 11:6
New King James Version (NKJV)
6 And if by grace, then it is no longer of works; otherwise grace is no longer grace.[a] But if it is of works, it is no longer grace; otherwise work is no longer work.
- Davies
Jesus restores mankind's relationship to God to each of us individually when we become born again. No one can do any works, either righteous works or works of the law of Moses to earn this grace from God.
Adam severed mankind's spiritual relationship with God when he sinned. No human being could repair this damage.
Only Jesus Christ who is both God and Man could be a Mediator between God and mankind and this is because only He is both God and Man. Only He could be a Mediator and so He did choose to pay the price (ransom) for mankind's redemption from mankind's slavery to sin which was the consequence of Adam's sin. Jesus Christ repaired the severed spiritual relationship between God and mankind. He saved us from the curse of continued slavery to the consequences of Adam's sin.
Now, each person has the possibility of inheriting eternal life. Before Jesus redeemed mankind, there was no hope or no possibility of inheriting eternal life. Now, we have hope of inheriting eternal life.
Titus 3:4-7 But when the goodness and loving kindness of God our Savior appeared, 5 he saved us, not because of works done by us in righteousness, but according to his own mercy, by the washing of regeneration and renewal of the Holy Spirit, 6 whom he poured out on us richly through Jesus Christ our Savior, 7 so that being justified by his grace we might become heirs according to the hope of eternal life.
Hope of eternal life is not a guarantee of eternal life. I hope to win the Publisher's Clearing House Sweepstakes. but my hope may indeed be in vain. :D
1 Peter 3:15 but in your hearts honor Christ the Lord as holy, always being prepared to make a defense to anyone who asks you for a reason for the hope that is in you; yet do it with gentleness and respect,
People who either knowingly believe or knowingly teach error lose their salvation. There is only one gospel of Christ, but there are many people who pervert His gospel and claim that their perverse teaching is the true gospel:
Galatians 1:6-7 I marvel that you are turning away so soon from Him who called you in the grace of Christ, to a different gospel, 7 which is not another; but there are some who trouble you and want to pervert the gospel of Christ.
2 Timothy 3:1-7 But understand this, that in the last days there will come times of difficulty. 2 For people will be lovers of self, lovers of money, proud, arrogant, abusive, disobedient to their parents, ungrateful, unholy, 3 heartless, unappeasable, slanderous, without self-control, brutal, not loving good, 4 treacherous, reckless, swollen with conceit, lovers of pleasure rather than lovers of God, 5 having the appearance of godliness, but denying its power. Avoid such people. 6 For among them are those who creep into households and capture weak women, burdened with sins and led astray by various passions, 7 always learning and never able to arrive at a knowledge of the truth..
Many people claim to be Christians (they have the outward appearance of godliness), but they do not live a Christ-like life. They will not inherit eternal life.
Titus 1:16 They profess to know God, but in works they deny Him, being abominable, disobedient, and disqualified for every good work.
2 Timothy 2:19 Nevertheless the solid foundation of God stands, having this seal: “The Lord knows those who are His,†and, “Let everyone who names the name of Christ depart from iniquity.â€
Many sinful people call themselves Christians and they claim that they will inherit eternal life, but they will not:
Galatians 4:11 I am afraid for you, lest I have labored for you in vain.
1 Thessalonians 3:5 For this reason, when I could no longer endure it, I sent to know your faith, lest by some means the tempter had tempted you, and our labor might be in vain.
