It's like I said, which is what God's Word shows, that "sons of God" phrase is a pointer to the heavenly state. Don't listen to men's traditions, read your Bible...
1 John 3:1-2
3 Behold, what manner of love the Father hath bestowed upon us, that we should be called the sons of God: therefore the world knoweth us not, because it knew Him not.
2 Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when He shall appear, we shall be like Him; for we shall see Him as He is.
KJV
Those of Faith are now called... "the sons of God". In the simplest sense, it means God's children. Yet it also refers to the heavenly body state, because Apostle John in verse 2 above is revealing how when Lord Jesus does return, we will see Jesus in His heavenly body as He really is, and we also will have a heavenly body like His. Recall the change at the twinkling of an eye that is to happen on the "last trump" per Apostle Paul in 1 Cor.15.
Likewise, that "sons of God" phrase is used in The Old Testament only about the angels. Why? It's because the angels are in the heavenly state (See Job 1 & 2, and Genesis 6). Those who try to confuse this issue appear to point to those who reject that the "sons of God", or a group of Satan's angels, left their heavenly state, came to earth, and mated with the flesh daughters of Adam to produce the giant-hybrid race shown in God's Word.
Matt 22:29-32
29 Jesus answered and said unto them, "Ye do err, not knowing the scriptures, nor the power of God.
30 For in the resurrection they neither marry, nor are given in marriage, but are as the angels of God in heaven.
31 But as touching the resurrection of the dead, have ye not read that which was spoken unto you by God, saying,
32 I am the God of Abraham, and the God of Isaac, and the God of Jacob? God is not the God of the dead, but of the living."
KJV
That "... as the angels of God in heaven" is Jesus simply pointing to the heavenly body state. Per Apostle Paul in 1 Corinthians 15, the type body of the resurrection of the world to come is a "spiritual body". And here is more of that which Paul taught that many struggle with - in 2 Corinthians 5, Apostle Paul taught that already, we have a 'spirit' body that is eternal in the heavens that dwells inside our flesh body. When our flesh body dies, our other body, our 'spirit' body is loosed, and goes back to The Father Who gave it to us (See Ecclesiastes 12:5-7).
