Most claim that the narrow way and the broad way separates the saved from the lost.
Only Christians are currently saved, as long as they remain faithful until their death. Everyone else is unsaved - they will be saved during Christ's 1,000 years reign. Christians will have the honour and pleasure of sharing Christ's reign, helping to restore everyone back to human perfection.
Thus alleging that God is making sport of our eternal destination. "Few there be that find it..."
Not everyone is called to become part of God's new creation, to become members of the body of Christ - most are destined to remain part of God's human creation. For example, nobody who lived before Christ's ministry could be called, which is why Jesus said, in Matthew 11:11 (WEB), "Most certainly I tell you, among those who are born of women there has not arisen anyone greater than John the Baptizer; yet he who is least in the Kingdom of Heaven is greater than he". The whole world has never been wholly converted to Christianity, and it won't be until Christ's 1,000 year reign.
Romans 8:28-30 (WEB):
(28) We know that all things work together for good for those who love God, to those who are called according to his purpose.
(29) For whom he foreknew, he also predestined to be conformed to the image of his Son, that he might be the firstborn among many brothers.
(30)
Whom he predestined,
those he also
called. Whom he called, those
he also justified. Whom he justified, those
he also glorified.
Ephesians 1:4-5 (WEB):
(4) even as he chose us in him before the foundation of the world, that we would be holy and without defect before him in love;
(5) having predestined us for adoption as children through Jesus Christ to himself, according to the good pleasure of his desire,
Although I probably don't agree with your conclusion. Salvation by works?
Correct me if I am misunderstanding you, thanks.
Salvation comes from Jesus' sacrifice, condemnation comes from our works. By Adam's works we were all condemned to death. We are all saved from death resulting from Adam's sin (and our inherited sinful nature), by Jesus' redeeming sacrifice. Whether or not we will have eternal life will be dependent on our works. For most that will be their works after their resurrection, during Christ's 1,000 years reign. For Christians, God works in us, Philippians 2:13 (WEB):
(13) For it is God who works in you both to will and to work, for his good pleasure.
but Christians have to work too, 2 Peter 1:4-10 (WEB):
(4) by which he has granted to us his precious and exceedingly great promises; that through these you may become partakers of the divine nature, having escaped from the corruption that is in the world by lust.
(5) Yes, and for this very cause adding on your part all diligence, in your faith supply moral excellence; and in moral excellence, knowledge;
(6) and in knowledge, self-control; and in self-control perseverance; and in perseverance godliness;
(7) and in godliness brotherly affection; and in brotherly affection, love.
(8) For if these things are yours and abound, they make you to be not idle or unfruitful in the knowledge of our Lord Jesus Christ.
(9) For he who lacks these things is blind, seeing only what is near, having forgotten the cleansing from his old sins.
(10) Therefore, brothers, be more diligent to make your calling and election sure. For if you do these things, you will never stumble.
