Of course it's the heart. No question.
Does a sinning heart want to honor and love God?
I'd say no----no matter at what point in life this happens.
Before salvation or after salvation.
If we fall back into a sinful life, then we must repent again.
Yes, I agree: Repentance is necessary no matter which side of conversion one is on. In God's family or outside of it, repentance is definitely required. The repentance of a lost person, though, is necessarily different from that of a born-again person. A lost person's repentance is from an entire life lived in rebellion toward God and His Truth; a saved person's repentance is from a contrary-to-identity lapse into self-will and sin, not from total spiritual unregeneracy.
Does a sinning heart desire God? If it was impossible for such a heart to do so, no one would be saved; for all of us are saved out of lives given over to Self and sin, in flagrant rebellion toward God (Titus 3:-35; Ephesians 2:1-9; Colossians 1:21-22). It's no surprise, then, that a saint, though having fallen into sin, still desires to live better, to return to holy fellowship with God. Their sin does not eradicate all desire for God; though, if they persist in their sin, that desire will, in time, cool and eventually disappear entirely. This condition does not develop overnight, after a single wayward moment, but is a progressive thing, continuing against the convicting work of the Holy Spirit (John 16:8), and the discipline of God (Hebrews 12:5-11).
Ephesians 2:8 states that we are saved by God's grace through faith.
If we have faith, we're saved.
If we do not have faith, how could we be saved?
Nowhere that I can think of in scripture is it stated that we could be saved without faith.
If you have a verse, let me know.
I don't think I indicated that faith had no part to play in bringing a lost person to salvation... Faith, though, doesn't save us. There is only one Savior, only one who can save, and to his saving work we can contribute nothing. Our faith simply puts us in the place where he saves us.
Can't agree with this Tenchi.
God knows no time constraints.
God had already resolved the problem of sin in the Garden.
Jesus has atoned for man's sin from the beginning of time.
Even those in the OT were saved because of Jesus atoning death.
ALL mankind is saved through the propitiatory death of Christ.
1 John 2:2
2and He Himself is the propitiation for our sins; and not for ours only, but also for those of the whole world.
When, in the Sermon on the Mount in Matthew 5-7, Jesus spoke to his Jewish audience who were still under the Old Covenant (he had not yet made a New Covenant through his atoning work at Calvary), none of them were born-again, as Jesus told Nicodemus he had to be (John 3:5-7). So, though, Jesus's sacrifice of himself on the cross had a retroactive effect, until it had occurred, the Jews were still operating under the old, law-centered, Mosaic Covenant. In light of this, Jesus spoke in his Sermon on the Mount to his mainly Jewish audience in an Old Covenant way, setting a standard for holiness for them beyond the already unattainable Mosaic Law, thus setting the stage for his "new and living way" which would achieve, not mere reconciliation with God, but fellowship with Him (Hebrews 9 -10:22).
I don't see the Sermon on the Mount, then, as addressing Christians under the New Covenant, instructing them on how to live as born-again people or defining the dynamics of their relationship to God as His forever-redeemed children.
I don't understand what the difference would be.
I find it ironical that you would include Hebrews 10:19 for support of your belief.
Hebrews 10:23 warns us that we are TO HOLD FAST the confession of our hope without wavering.
Hebrews 10:11-25
11 And every priest stands daily at his service, offering repeatedly the same sacrifices, which can never take away sins.
12 But when Christ had offered for all time a single sacrifice for sins, he sat down at the right hand of God,
13 waiting from that time until his enemies should be made a footstool for his feet.
14 For by a single offering he has perfected for all time those who are being sanctified.
15 And the Holy Spirit also bears witness to us; for after saying,
16 “This is the covenant that I will make with them after those days, declares the Lord: I will put my laws on their hearts, and write them on their minds,”
17 then he adds, “I will remember their sins and their lawless deeds no more.”
18 Where there is forgiveness of these, there is no longer any offering for sin.
19 Therefore, brothers, since we have confidence to enter the holy places by the blood of Jesus,
20 by the new and living way that he opened for us through the curtain, that is, through his flesh,
21 and since we have a great priest over the house of God,
22 let us draw near with a true heart in full assurance of faith, with our hearts sprinkled clean from an evil conscience and our bodies washed with pure water.
23 Let us hold fast the confession of our hope without wavering, for he who promised is faithful.
24 And let us consider how to stir up one another to love and good works,
25 not neglecting to meet together, as is the habit of some, but encouraging one another, and all the more as you see the Day drawing near.
This passage describes a state-of-affairs between God and the New Covenant believer that none to whom Jesus was speaking in the Sermon on the Mount in Matthew 5-7 knew anything of, and certainly did not enjoy. Of course, it was impossible that they should, Christ's sacrifice of himself not yet accomplished. When I read this passage and consider how different the dynamic is between myself, a born-again child of God, and those who labored under the Old Mosaic Covenant, I understand how...tertiary Jesus's words in Matthew 7:21-23 are to my life as a New Covenant Christian.
In any case, I don't see Hebrews 10:23 as a warning, but as an exhortation arising from what has been laid out in prior verses about the "new and living way" in which born-again believers stand relative to God. It simply stands to reason that, in light of verses 11-18, verse 23 should follow. This is all it seems to me that the writer of Hebrews is saying in verse 23. Why wouldn't the born-again person "hold fast" such awesome, peace-making, fear-dissolving truth, fully assured of God's acceptance (vs. 22)?
