Of course one cannot merit salvation--Christ alone could do that. However, scripture is equally and abundantly clear that if your life is not characterized by obedience, you will not see the kingdom of heaven.
"Not everyone that says to Me, 'Lord, Lord' shall enter the kingdom of heaven, but he that does the will of my Father in heaven." --Matt 7:21
Unfortunately, you completely misundestood the Lord's words here. The will of the Father for entrance into heaven is that your righteousness must "exceed" the righteousness of the best of religious men (Mt. 5:20) and EQUAL the best of God (Mt. 5:48). This is the "rock" or "foundation" that Jesus goes on to speak about upon which ones life "house" must be built if it is to withstand the judgement (rains, floods). There is no distinction between the "house" (life) that collapsed and the "house" that stood firm - the difference was the foundation. A "rock" is a solid object whereas "sand" is a MIXTURE and that is precisely the profession of those Christ said he "NEVER" knew
"Lord, Lord.......HAVE WE NOT DONE..."
Their claim was exactly what you claim - faith in Christ ("Lord, Lord") plus a pious religious life and yet they went to hell. It is not that they were once saved and then lost, but he said that he "NEVER" knew them.
That is your first problem, you don't distinguish between justificaiton and regeneration and if you do, you obviously do not understand either one and what they are designed to accomplish in regard to your person and position.
If a branch in Christ (ie regenerated and justified) does not abide in Christ, he will be cut off as a branch and be no longer justified. (John 15:1-6)
Jesus is not talking about gaining heaven here at all nor is he talking about maintaining entrance into heaven. He said they were already cleansed through the word (v. 2). He is talking about producing "fruit" for God's glory and for their own benefits (joy, answered prayer, etc.).
When a limb is pruned, it is cutting part of it off. This is what the husbandman (the Father) does to every branch in order to produce more fruit. However, if after pruning by the husbandman, there is no fruit, then "men" (not the Father) cut off the limbs and burn them. Their profession before men is destroyed just as salt that loses its flavor is trampled under the feet of men or considered worthless.
In contrast, if fruit is produced NOT ONE WORD IS SAID ABOUT THAT OBTAINING HEAVEN! What is obtained, is joy, answered prayers, closer communion with Christ.
The verse clearly states He is the "author of eternal salvation to all who obey Him", your dismissal of the clear meaning (because it doesn't apparently jive with your preconceived theology) notwithstanding.
"He became the author of eternal life to all who obey Him." Hebrews 5:9
Let's put the text in its context:
Heb. 5:8 Though he were a Son, yet learned he
obedience by the things which he suffered;
9 And being made perfect, he became the author of eternal salvation unto all them that
obey him;
Jesus Christ did not obey in order to be the Son of God. He obeyed because he was the Son of God. Likewise with other begotten children of God. They do not obey in order to become a child of God, they obey because they are children of God. Remember the beattitudes? "Blessed ARE....Blessed ARE...."
No human obeys in order to become, they obey because they "ARE" children of God. There is obedience to the gospel (repentance and faith) but that is "with the heart man beleiveth unto righteousness" and that is the condition of the "new" heart when it is given in regeneration - it is a beleiving heart whereas the old heart was "at enmity with God and not subject to the loaw of God and neither indeed can be."
You made an assertion without backing it up. Romans 2:13 states: "for not the hearers of the law are just in his sight, but the doers of the law will be justified." (Oops)
That is the terms of justification by the law! In order to be justified by the law just as I quoted Paul who puts the same thing in a negative form:
Cursed is every one that continueth not in all things which are written in the book of the law to do them.
Take note of Romans 2:1-3 - this is not a description of beleivers but of of self-righteous HYPOCRITS who believe they will escape judgement by their own works:
3 And thinkest thou this, O man, that judgest them which do such things, and doest the same, that thou shalt escape the judgment of God?
Take note of Romans 2:4 that this is about those who despise God's forebearance and longsuffering with their hypocrisy, that should lead them to repentance rather than despising God:
4 Or despisest thou the riches of his goodness and forbearance and longsuffering; not knowing that the goodness of God leadeth thee to repentance?
Take note of Romans 2:5 that this is about those who are hardened in their own HYPOCRTICAL SELF-RIGHTEOUSENSS believing they will pass the judgement of God over others:
5 But after thy hardness and impenitent heart treasurest up unto thyself wrath against the day of wrath and revelation of the righteous judgment of God;
Take note of Romans 2:6. It is this class of SELF RIGHTEOUS HYPOCRITES who believe they shall escape the judgement of God over others that Paul then goes on to spell out what the JUST principles that will be employed by God in the judgement of those who come to him by their OWN RIGHTEOUSNESS. Gods' judgement will be completely just rather than biased but will be based strictly upon the MERITS OF THEIR OWN WORKS according to the Standard of God's Law:
6 Who will render to every man according to his deeds:
The fair and just judgement of God's law will render the right verdict as the works demand:
7 To them who by patient continuance in well doing seek for glory and honour and immortality, eternal life:
8 But unto them that are contentious, and do not obey the truth, but obey unrighteousness, indignation and wrath,
The fair and just judgement of God's law will judge every man fairly according to the light he received. Since the self-righteous Jew received more light he will be judged above the self-righteous Gentile who received less light:
9 Tribulation and anguish, upon every soul of man that doeth evil, of the Jew first, and also of the Gentile;
10 But glory, honour, and peace, to every man that worketh good, to the Jew first, and also to the Gentile:
The Jew he is speaking of is fully described in verses 17-24.
The fair and just judbment of God's Law will not respect anyone's person but judge SELF-RIGHTEOUS men fairly according their own personal light:
11 For there is no respect of persons with God.
12 For as many as have sinned without law shall also perish without law: and as many as have sinned in the law shall be judged by the law;
This is judgement according to God's Law in order to be justified by the Law according to what you do not according to what you know:
13 (For not the hearers of the law are just before God, but the doers of the law shall be justified.
This text has nothing to do with the judgement of rewards for the saints as the saints will never stand before the Law of God in order to be justified by their own works because they have already been justified FREELY BY GRACE THROUGH CHRIST - Rom. 3:24-26
This whole context is about SELF-RIGHTEOUS HYPOCRITS who believe they shall escape the judgement of God by their own works. This is judgement of the lost and this is judgement for justification under the law according to their own works. No Christ, No faith, no salvation mentioned here in this context. He continues to describe the kind of person this refers to in Romans 3:17-3:20.
