Whole world is not each and every person who ever lived. It means not just Jews, but all other nations are included.
But of couse it's not each and every person that has ever lived,it's those who are alive as these events unfold
As I've said anyone who is not in Christ are already deceived,therefore only Christians can be deceived and many will be,hence the below verses
Matthew 7:21 "Not every one that saith unto Me, 'Lord, Lord,' shall enter into the kingdom of heaven; but he that doeth the will of My Father Which is in heaven."
Matthew 7:22 "Many will say to Me in that day, 'Lord, Lord, have we not prophesied in Thy name? and in Thy name have cast out devils? and in thy name done many wonderful works'.
Matthew 7:23 "And then will I profess unto them, 'I never knew you: depart from Me, ye that work iniquity' ."
Jesus Christ is saying here, and you had better get this now, when there is time. If you do not follow the path that Jesus Christ is teaching you in this sermon on the mount, Jesus response to you will be, "I never knew you: depart from me, ye that work iniquity".
This is the generation that better know the difference between God's doctrine and the doctrines of demons. They both sound very good, and they both sound right and true. However, any doctrine that isn't one hundred percent backed by the Word of God is a fake. So the time is here to get down and know what is in the Scriptures.
Both Christ and the devil offer peace, and prosperity, however, only Jesus Christ can offer eternal life. The eternal life should be foremost in the doctrine. Why does Jesus not want them? They worship the traditions of Men, and their church system, and they in fact do not even teach God's letter to His children. What they do quote from the Bible is twisted to satisify their own desires.
Matthew 7:24 "Therefore whosoever heareth these sayings of Mine, and doeth them, I will liken him unto a wise man, which built his house up a rock."
Jesus is telling each of us that if we are to be His, then we will listen to each thing that He has taught, and then go and put them into practice in our lives. Those instructions will sink into our hearts and minds, and we will be open to the Holy Spirit of God to lead us in our lives. We will strive to be like our Lord and Savior, and pattern our lives after Him. We will learn and practice the love that Christ showed to us, and give that love and kindness to our neighbor. We will learn all about the Kenites, and the laws and commandments of God. We will learn discernment of spirits and the good and bad teachers. We will learn it all; and then we will do it.
That "Rock" is Christ Himself. The victors will sing the "song of Moses" in the Millennium age as recorded in Deuteronomy 32. In verses 3, 4; "Because I will publish the name of the Lord: ascribe ye greatness unto you God. He is the Rock, His work is perfect: For all His ways are judgment: just and right is He." Those that love the Lord know the difference between the Rock Christ, and the spotted crooked rock of the devil. This generation will be tested by the little rock, the Antichrist, and many will leave Christ, and run in ignorance to the false Christ.
