What is so hard about believing that God's only elect nation of Israel
is in Christ and consists of Christians?
Your words are an insult to all the Jewish Christians who live in Israel - a good few thousand of them - and outside Israel, today.
Your words are also an insult to all the Jews who became Christians over the last 2,000 years.
In fact, your words are an insult to the apostles and all Jewish Christians of the first century who were persecuted for their faith by both Jew and Rome alike - you know? The remnant of the nation of Israel - who are called Israel in Romans 11?
It's clearly you alone who does not believe there is a nation called Israel that consists of Christians. The Bible teaches otherwise.
What's so hard about believing that the nation of China will consist of Christians?
What's so hard about believing that the nation of Indonesia will consist of Christians?
What's so hard about believing that the nation of Libya will consist of Christians?
Are all Americans, Europeans, Australians etc Christians? Or is it just a remnant in each nation?
What's so hard about believing that the nation of Israel would have a remnant - and has had a remnant since the 1st century, till now?
Are you calling Jesus a liar?
"For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. For God sent not his Son into the world to condemn the world; but that the world through him might be saved.
He that believeth on him is not condemned:
but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God. And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil." (John 3:16-19).
You are not only calling Jesus a liar, you are also calling His apostles liars:
"The Lord is not slack concerning his promise, as some men count slackness;
but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance." (2 Peter 3:9).
This is the end date for Jew and Gentile:
"But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up." (2 Peter 3:9-10).
