"It is the same today, for a 'few' of the people of Israel have remained faithful because of God's grace;" (Romans 11:5)
"Because of what Jesus said, 'many' of His disciples turned their backs on Him and stopped following Him." (John 6:66).
"Someone asked him, 'Lord, are only a 'few' people going to be saved?' Jesus answered: 'Work hard to enter the narrow door to God's Kingdom, for 'many' will try to enter but will fail.'" (Luke 13:23-24)
"Enter through the narrow gate because the gate and road that lead to destruction are wide. 'Many' enter through the wide gate. But the narrow gate and the road that lead to life are full of trouble. Only a 'few' people find the narrow gate." (Matthew 7:13-14).
"On the judgment day 'many' will call Me their Lord. They will say, 'We preached in Your name, and in Your name, we forced out demons and worked many miracles.' But I will tell them, 'I never knew you. Get away from Me, you who break God's laws.'" (Matthew 7:22-23)
The paradigm of majority and minority in the Scriptures is loud and clear.
It is, in fact, a plain and simple prophecy:
Many are called to be Christians, but few will receive eternal life.
Many are called to be Christian teachers and preachers, but few will enter the Kingdom of God.
Many of them claim that they know Jesus, but in fact, Jesus never 'knew' them.
To know Jesus is important. However, to be 'known' by Jesus is more important.
