Christians claims Jesus (PBUH) to be Son of God, but Bible describes many others Sons of God, besides Jesus (PBUH). So Christians' claim about Jesus (PBUH) to be the only begotten Son of God is fake:
Son of God No 1; Adam.
(Luke 3:38) Which was the son of Enos, which was the son of Seth, which was the son of Adam, which was the Son of God.
Son of God No. 2; Israel.
(Exodus 4:22) "Then you (Moses) shall say to Pharaoh" Thus says the LORD "Israel is my Son, My Firstborn."
Israel was Jacob, the father of Jewish nation. In Islam he is known as Yaqub, and Bani-Israel was his nation.
Son of God No. 3; Ephraim.
(Jeremiah 31:9) With weeping they will come; and by supplication I will lead them; I will make them walk by streams of waters; on a straight path in which they will not strumble; for I am a father of Israel, and Ephraim is my Firstborn.
Ephraim was the son of Joseph (Yusuf), and ancestor of one of the tribes of Israel.
Son of God No. 4; David.
(Psalm 2:7) I wil surely tell of decree of the LORD; He said to me "You (David) are my Son, today I have begotten you."
The above verse falsifies Christians' claim that Jesus was the Only Begotten Son of God, because the above verse says that David was also the Begotten Son of God.
Son of God No. 5; Solomon.
(1 Chronicles 28:6) He (God) said to me (David) "It is Solomon your son who shall build my house and my courts, for I have chosen him to be My Son, and I will be his Father."
Son of God No. 6; Jesus.
(Mark 1:1) The beginning of the gospel of Jesus Christ, the Son of God.
So, God has Six Sons named in the Bible. But they are not the total, because besides these Six, God also has many other Sons according to the Bible, and their number is in billions:
All people on earth are Sons of God.
(Matthew 23:9) And call no man your father upon the earth, for one is your Father, which is in heaven.
So, all people on the earth, should not call their fathers as "father", because according to the Bible, their father is God, living in heaven. And thus, God has billions & trillions of Sons!!!
Jews also called themselves Son of God.
Also at Jesus' time, all Jews considered themselves as Sons of God:
(John 8:41) Then said they (Jews) to him (Jesus) "We be not born of fornication; we have One Father (even) God."
So now it is rubbish to consider Jesus as Son of God, because if he is the Son of God, then according to the Bible, every man on the earth is Son of God.
