Hi, I see that differently in regard to how the word antichrist singular, or antichrists plural work seeing they have a different functions
The question I would ask is, which Israel seeing all Israel is not the same Israel ? This seeing God uses the word Israel in two ways. (#1) those who have the Spirit of Christ in them called Emanuel , meaning God with us, as the bride of Christ which in the book of Acts he named "Christian" ..... denoting residents of the City of Christ named after her founder, Christ the husband. The saints on the other side of the cross having the same excellency in their bodies of death as us today... "Emmanuel"
And the other(#2) Israel natural unconverted man as a gentle.
2 Corinthians 4:7 But we have this
treasure in earthen vessels, that the
excellency of the power may be of God, and not of us.
God named Jacob at birth a word meaning "deceiver" later his name was name was changed to "Israel" meaning as member of the kingdom of priests a prince(God calls us kings) a person that has power with God
and with men, and has prevailed through Emmanuel ...God with us.
Genesis 32:27-29 King James Version (KJV) And he said unto him, What is thy name? And he said, Jacob. And he said, Thy name shall be called no more Jacob, but Israel: for as a prince hast thou power with God and with men, and hast prevailed. And Jacob asked him, and said, Tell me, I pray thee, thy name. And he said, Wherefore is it that thou dost ask after my name? And he blessed him there.
Scriptures reveals many antichrists were there at the time 1 John was written .The Jews that denied Christ had come in the flesh as the fulfillment of prophecy are considered antichrists . I think today they might find some of the extreme groups that say a person must become a outward Jew and must be taught by man seen, relating to the flesh of a nation.... before they can be a member of the bride of Christ.
The veil is still rent.
They that refused to hear all things written in the law and the prophets as God's word to men as that needed to hear the gospel just as their gentile brothers God putting no difference between a Jew and a gentile purifying the hearts of both by a work of his faithfulness . I believe that is what the Holy Spirit is informing us of.
Acts 15:8-10 King James Version (KJV) And God, which knoweth the hearts, bare them witness, giving them the Holy Ghost, even as he did unto us; And put
no difference between us and them, purifying their hearts by faith. Now therefore why tempt ye God, to put a yoke upon the neck of the disciples, which neither our fathers nor we were able to bear?
The time of reformation came two thousands years ago a "great tribulation" for a outward Jew trusting in his flesh one like ever before, or ever again .
1 John 2:21-23 King James Version (KJV) I have not written unto you because ye know not the truth, but because ye know it, and that no lie is of the truth. Who is a liar but
he that denieth that Jesus is the Christ?
He is antichrist, that denieth the Father and the Son Whosoever denieth the Son, the same hath not the Father: he that acknowledgeth the Son hath the Father also.
They rejected both the father and the son in exchange for the oral traditions of men called a law of the fathers(
Acts 22:3. )A law that made the law of our one Father in heaven to no effect.
