Then I was right. in your view, His salvation is in peril.
Do you have any idea why some remain and others fall away? The Bible explains it,
The term "contingency" helps draw out the mistake that you and the others are making and the mistaken conclusion on which you land. We already discussed that many of Jesus' conditional statements are descriptive, not prescriptive. For instance, he speaks about a man who builds his house on sand. Here, our Lord sets up the preestablished status of the man's house. Then he notes that his house will not weather the storm.
We talked about the parable of the sower, which is also descriptive of a man's heart. One soil was cultivated and prepared beforehand to believe the word and persevere to the end. Jesus says they will persevere and "bear fruit." And what is THE FRUIT if not Salvation of the soul and eternal life?
So let's talk about the following conditional statement.
John 8:30-32
31 So Jesus was saying to those Jews who had believed Him, “If you continue in My word, then you are truly disciples of Mine; 32 and you will know the truth, and the truth will make you free.”
In light of the parable of the sower, what does Jesus mean? He is talking to a group of believers. Some will continue in his word, while others will not. Does he mention a loss of salvation here? Not explicitly, no, but He does talk about being set free (from sin) which is essentially the salvation message. Obviously, those who fail to continue in his word will not be liberated in the way Jesus means.
With regard to your view, note that the liberation takes place in the future at a time when the disciples who continued in his word will finally attain the freedom they wanted and valued. The truth will make you free (future tense) This idea is compatible with Jesus parable of the sower, where we see three people who began as believers but only one believer persevered. They are like the true disciple of Jesus who continued in his word.
Given that salvation comes after perseverance, then how can you say that the other people lost their salvation? Those who continue in Jesus' word WILL (Future tense) be freed. In the conditional statement above, salvation is not a present condition, but a future promise for those who continue in his word. They don't lose their freedom from sin. They never had that. Only those who continue in Jesu word will gain it.
Did you fail to read the passages I gave you? In the parable of the sower, the only believer who persevered is the believer whose heart was cultivated by the farmer. (God) We discussed passages from three different apostles, each making the case that a person should exult, count it Joy, and consider that the testing of our faith is more precious than gold. Why, if not for the reason that it proves something to the believer? In Jesus' parable, a believer fell away because he was suffering a great testing (the heat of the sun) and he gave up. But one of the seeds fell on the cultivated soil and it didn't fall away. Jesus concludes that it was the heart condition that made the difference.
Whether a man will fall away or not depends on his inwardness, which is only accessible by God himself. No one can change a man from the inside out except God.
