"Now there was a man in Jerusalem, whose name was Simeon, and this man was righteous and devout, waiting for the consolation of Israel, and the Holy Spirit was upon him. And it had been revealed to him by the Holy Spirit that he would not see death before he had seen the Lord's Christ" (Luke 2:25-26, ESV).
It is normal for us to have an idea or belief so fixed in our minds that we fail to see or read what the biblical text means.
For example, Simeon was filled with the Holy Spirit long before the events found in the Book of Acts.
Simeon states a profound Truth about the Messiah.
The Messiah would be "a light for revelation to the Gentiles, and for glory to your people Israel" (Luke 2:32, ESV).
If someone believes that all "Jews" had rejected the coming Messiah, how can Scripture declare that Christ is "for the glory to your people israel"?
One may say that the rejection occurred later. Not so per the Bible. The Twelve Apostles were all good old Jewish boys; men of Israel.
It is not a person's opinion that determines his or her final, eternal destiny. It is what a person does with God's Word. If a person rejects the Word of God, fails to live according to the teachings of the whole Bible, they are rejecting Christ. Note: The Word of God is in fact the man Christ Jesus since the Word became flesh (John 1:14).
"If you love me, you will keep my commandments" (John 14:15, ESV).
Jesus spoke these words about three hundred years before there was a document call the New Testament. God determines the rules, not religious leaders.
