What I'm sure we agree on, is that salvation is "Christ-in-us". Thus it's not a "saved-in-the-FUTURE" thing, it's "saved now, and saved in the future too if we persevere".We are to be 'pregnant with Christ', yes, ie he must be formed in us. But only those who bring this to completion get the reward.
Throughout Scripture are references to "saved, if we CONTINUE/HOLD-FAST". Col1:21-23, 2Cor15:2, Heb3:6 & 15, etcetera.This life is like a probation period after being hired. Yeah, either you are OR you aren't hired, it's all or nothing in that sense. But if one shows himself to be unfit for the job, he doesn't make it through. Can we say he never had the job? No. But we can say he didn't make it through probation.
1Cor15:1-2 "Now I make known to you, brethren, the gospel which I preached to you, which also you received, in which also you stand,
by which also you are saved, if you hold fast the word which I preached to you, unless you believed in vain.
Philip2:16 also has Paul judging his own success in terms of his followers' persevering in salvation.
The concept of "being deceived away from God" is replete in Scripture; we're at the same risk as Eve was. (2Cor11:3.)When one gets the job, he gets the necessary tools right away... That is grace. And if he becomes able to do more work, different things, he receives the missing tools. That is grace, anointing, the empowerment of God to serve him. Such a person is partaking in eternal life, working in the kingdom. But that is no guarantee of what end they will meet.
Matt22:14. Context is important --- the "many" is "everyone-you-find", and the "few" are those who came (and put on clean clothes).Rather this person could get the job, but then not last. Many are called, few are chosen.Here too it's important to understand what is being taught. Does the seed flourish because the ground is "good"? Or is the ground called "good", if the seed flourishes? Contextually, it's the latter; Heb6:7-8 applies, one field is tilled expecting to reap good fruit --- if it does the ground is blessed, but if it yields thorns and thistles it is cursed and burned.To give an example, at my job, I was hired along with 6 other guys... We were all supposed to start on the Monday. To start off, 3 guys didn't show up. Then one of them quit soon after starting. One worked with me for a bit till he found another job. Another lasted until we had a 3 month layoff (this is usual at my job, we work about 9 months a year), and I haven't seen him since.
Some of the seed falls on the rocks, nothing comes of it. Some of it falls among weeds and thorns, it grows quickly but doesn't last. Some of it falls on shallow ground, goes up fast, but when it cant reach enough water to support it, it dies. And then some falls on the good ground, and bears fruit.
Ironically, I like thistles; bright purple tufts of flowers with a good fragrance. If they grow in my yard I do NOT cut them down... :-P
As long as we all agree that "by their fruits they will be known", we have enough to stand together. I am concerned if and when someone teaches "backslidden-but-saved", that is they are bearing bad fruit but will still waltz into Heaven...Can we say that those who worked there shortly never worked there? Not really. Further, can we say those who didn't show up on the Monday were never hired? No, they were! Rather they didn't endure.
God freely invests grace on whoever will give the job a shot... And it will not return to him void. But that means it will not return with NO fruit... But it won't return with ALL fruit either.
