Actually, you never showed that. I, however, showed that Jesus clearly says that He gives His sheep eternal life. And He loses none of them. So your premise has been proved, from scripture, to be a falsehood.
Our Lord doesn't lose a sheep, that is clear.
There are many NT verses warning a believer not to depart from the faith. They can not leave it if they weren't in it to begin with. In the OT, a passage from Ezekiel sums it up quite well too. However, many people will dismiss it simply because it was in the old testament.
The new testament warns us not to be fooled by false leaders. Why do people believe theologians, who can err, more than the word of God? It takes a lot of explanation and twisting to make a few verses which don't say otherwise have more weight than the rest of it, which are calls to persevere and keep watch over ourselves.
I don't trust myself to think I have got it right, and I definitely do not trust past theologians who are just as likely to be confused. We can only trust in Him and lean on Him to direct our paths. Proverbs 3:5-6.
While writing this I read the whole of Galatians. Paul starts off despairing that they are tempted already by a Gospel different to the one he gave them. Then speaks about the law and grace and freedom. He explains about living in the Spirit and the works of the flesh. In Galations 5 Paul writes ''I warn you, as I did before, that those who live like this will not inherit the kingdom of God''
The warning is reiterated in Galatians 6 with:
"1Brothers and sisters, if someone is caught in a sin, you who live by the Spirit should restore that person gently. But watch yourselves, or you also may be tempted.
2Carry each other’s burdens, and in this way you will fulfill the law of Christ.
3If anyone thinks they are something when they are not, they deceive themselves.
4. Then they can take pride in themselves alone, without comparing themselves to someone else,
5for each one should carry their own load.
6Nevertheless, the one who receives instruction in the word should share all good things with their instructor.
7Do not be deceived: God cannot be mocked. A man reaps what he sows.
8Whoever sows to please their flesh, from the flesh will reap destruction; whoever sows to please the Spirit, from the Spirit will reap eternal life.
9Let us not become weary in doing good, for at the proper time we will reap a harvest if we do not give up.
10Therefore, as we have opportunity, let us do good to all people, especially to those who belong to the family of believers.
11See what large letters I use as I write to you with my own hand!''
I know you see it differently. I only started reading Galatians because I was going to quote the verse in chapter one about being deceived. However, in reading the entire epistle there are the arguments about grace etc all dealt with and still the call to persevere. Still the call to look out for each other that they don't stumble. To examine ourselves that we are still in Christ. Paul was writing to believers who were going astray.
