I forgot to include verse 5 of Isaiah 56 (KJV) about eunuchs receiving a blessing from Yahweh/the Lord. In context (Isaiah 56:3-5) it says the following.
"3 Neither let the son of the stranger, that hath joined himself to the Lord, speak, saying, The Lord hath utterly separated me from his people: neither let the eunuch say, Behold, I am a dry tree.4 For thus saith the Lord unto the eunuchs that keep my sabbaths, and choose the things that please me, and take hold of my covenant;
5 Even unto them will I give in mine house and within my walls a place and a name better than of sons and of daughters: I will give them an everlasting name, that shall not be cut off."
Verse 3 (in its reference to a "dry tree") makes me wonder if the type of eunuchs it speaks of are those who have crushed (or congenitally deformed) testes (or perhaps no testes) and no production of semen.
According to the Bible, Jesus said that in the resurrection there is no marrying for the resurrected ones are like angels. Does that mean that according to the Bible angels are sexless (in the sense of having no procreative powers) and that humans who become resurrected (at least for life in heaven) will also be sexless in the same sense? Matthew 22:29-30 (KJV) says the following.
"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."
Paul in Galatians 3:26-29 (KJV) says the following.
"6 For ye are all the children of God by faith in Christ Jesus.
27 For as many of you as have been baptized into Christ have put on Christ.
28 There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female: for ye are all one in Christ Jesus.
29 And if ye be Christ's, then are ye Abraham's seed, and heirs according to the promise."
The Gnostic Christian scripture in the Gospel of Thomas Saying 22 (as translated by Blatz) says the following about the sexes (see http://www.earlychristianwritings.com/thomas/gospelthomas22.html ).
"Jesus saw some infants who were being suckled. He said to his disciples: These infants being suckled are like those who enter the kingdom. They said to him: If we then become children, shall we enter the kingdom? Jesus said to them: When you make the two one, and when you make the inside as the outside, and the outside as the inside, and the upper as the lower, and when you make the male and the female into a single one, so that the male is not male and the female not female, and when you make eyes in place of an eye, and a hand in place of a hand, and a foot in place of a foot, an image in place of an image, then shall you enter [the kingdom]."
