Wow, @menrov, so you're suddenly a "believer".🙄
Well, interesting that you would choose to "believe" Paul's words at First Corinthians but not "believe" what is written in Acts, such as at 5:29 where it says "We must obey God".
But since you brought up 1 Corinthians 6:9-11...
"Or do you not know that unrighteous people will not inherit God’s Kingdom? Do not be misled. Those who are sexually immoral, idolaters, adulterers, men who submit to homosexual acts, men who practice homosexuality, thieves, greedy people, drunkards, revilers, and extortioners will not inherit God’s Kingdom. And yet that is what some of you were. But you have been washed clean; you have been sanctified; you have been declared righteous in the name of the Lord Jesus Christ and with the spirit of our God."
...maybe you noticed the first part of those verses: "unrighteous persons".
The definition of an "unrighteous" person in the Bible is one who does what is "not right" by God's standards.
The list at First Corinthians 6 there is not "all-inclusive". Murder isn't mentioned there either, but 1 John 3:15 says "Everyone who hates his brother is a murderer, and you know that no murderer has everlasting life remaining in him."
The Bible doesn't outright say that vampirism is "wrong", but it doesn't take a rocket scientist or a Rhodes scholar to figure out that vampirism is "unrighteous" according to God.
Whoever teaches that it is acceptable to take in blood or actually does it is the one with blood on their hands before God. The GB/FD$ are bloodguilty for many reasons, and giving tacit approval to medical procedures involving blood and blood fractions is just one of the reasons.
Abstaining from blood has been required by God from the beginning. It is written about throughout the Law, back from Abel's death at Cain's hands through Noah's time and the Mosaic Law to our day.
@menrov, you claimed that Acts is not a law from Jesus as far as requirements for entering into the Kingdom of the heavens. How about Jesus' own words...
"Do not think I came to destroy the Law or the Prophets. I came, not to destroy, but to fulfill. Truly I say to you that sooner would heaven and earth pass away than for one smallest letter or one stroke of a letter to pass away from the Law until all things take place. Whoever, therefore, breaks one of these least commandments and teaches others to do so will be called least in relation to the Kingdom of the heavens. But whoever does them and teaches them will be called great in relation to the Kingdom of the heavens. For I say to you that if your righteousness does not surpass that of the scribes and the Pharisees, you will by no means enter into the Kingdom of the heavens."
