We read three statements in 1 John 5:5-13 that appear to contradict the teachings of Jesus the Messiah from Matthew 8:10-11 & Matthew 22:30-22 regarding requirements of receiving eternal life.
In 1 John 5, we read :
 Who is he that overcometh the world, but he that believeth that Jesus is the Son of God?"
 He that hath the Son hath life; and he that hath not the Son of God hath not life.
 These things have I written unto you that believe on the name of the Son of God; that ye may know that ye have eternal life, and that ye may believe on the name of the Son of God.
But the teachings of Jesus in Matthew 8:10-11 and Matthew 22:30-32 state something different about who received eternal life. Yeshua of Nazareth specifically names three people (Abraham, Isaac, and Jacob) who are eternally living in Heaven & never knew the name of "Jesus" as the Son of God.
In Matthew 8:10-11 :
 Now when Jesus heard this, He was amazed and said to those who were following, “Truly I say to you, I have not found such great faith with anyone in Israel.  And I say to you that many will come from east and west, and recline at the table with Abraham, Isaac, and Jacob in the kingdom of heaven
In Matthew 22:30-32 - Abraham, Isaac, and Jacob received eternal life by recognizing YHVH as God :
 For in the resurrection they neither marry nor are given in marriage, but are like angels in heaven.  But regarding the resurrection of the dead, have you not read what was spoken to you by God:  ‘I am the God of Abraham, the God of Isaac, and the God of Jacob’? He is not the God of the dead, but of the living.”
And He said, "I am the God of your father, the God of Avraham, the God of Yitschaq, and the God of Yaqov." And Moshe hid his face because he was afraid to look toward God. ( וַיֹּ֗אמֶר אָֽנֹכִי֙ אֱלֹהֵ֣י אָבִ֔יךָ אֱלֹהֵ֧י אַבְרָהָ֛ם אֱלֹהֵ֥י יִצְחָ֖ק וֵֽאלֹהֵ֣י יַֽעֲקֹ֑ב וַיַּסְתֵּ֤ר משֶׁה֙ פָּנָ֔יו כִּ֣י יָרֵ֔א מֵֽהַבִּ֖יט אֶל־הָֽאֱלֹהִֽים )
Yeshua of Nazareth is quoting Exodus 3:6 when describing the eternal life of God's people in Matthew 22:30-33.
How could 'Abraham, Isaac, and Jacob' be living eternally in Heaven if they never believed the requirement in 1 John 5:5-13 to receive eternal life?
