I see a clause in I Corinthians that gives me all the faith in eternal security that I need. Our works for Christ will be judged and if any works are burned as wood, hay or stubble the Bible says that that believer shall suffer loss, yet he himself shall be saved, yet so as by fire.
We're not talking about works, nor are we saved by works. Salvation is obtained by faith in the shed blood of Christ. If anyone is not having faith, then their works are irrelevant.
You are using verses that Christ directed to Israel and assuming that they apply equally to the church.
That is not true. None of the scriptures that I used were directed at Israel. I used Paul's letter to the Corinthians and Jesus letters to the seven churches.
When the 'kingdom of heaven' is used to begin a parable - Jesus is speaking of the Millennium.
If that were true, then the kingdom of heaven, would not be the king of heaven. It would be a contradiction in terms. For example:
"In My Father’s house are many rooms. If it were not so, would I have told you that I am going there to prepare a place for you?
3And if I go and prepare a place for you, I will come back and welcome you into My presence, so that you also may be where I am."
In the scripture above, Jesus promises that that He is going to prepare places for us in His Father's house, which could only refer to heaven and which is synonymous with "the kingdom of heaven" and which does not infer the millennial kingdom and that because the millennial kingdom will be on earth.
Salvation is and has always been obtained through faith. No faith, no salvation. I given you examples and scripture. You can of course continue to believe what you do, but I will stay with what I have presented. Once again, here is what Paul said to the Gentile Colossians:
"But now he has reconciled you by Christ’s physical body through death to present you holy in his sight, without blemish and free from accusation—[IF] you continue in your faith, established and firm, and do not move from the hope held out in the gospel."
"For we have become partakers of Christ, [IF] we hold fast the beginning of our assurance firm until the end"
Both of those scriptures have conditions attached to them "if we continue in faith." We are not just saved to be saved, so that we can turn back to willfully living according to the sinful nature. If a believer turns back to the sinful nature, while in that state they are accumulating sin which leads to death. This is the truth of scripture. OSAS takes does away with the fear of God. Did you read the following scripture:
"But watch yourselves, or your hearts will be weighed down by dissipation, drunkenness, and the worries of life—and that day will spring upon you suddenly like a trap. For it will come upon all who dwell on the face of the whole earth. So keep watch at all times, and pray that you may have the strength to escape all that is about to happen and to stand before the Son of Man.”
The above is not to Israel, but to the church. Notice that, believers who fall back into dissipation, drunkenness and the cares of this life (sinful nature), Jesus said, that period of God's wrath will close on them that like a trap, meaning that they will be left here when He comes for the church to endure His wrath.
Pay attention to what these scriptures are saying.
