ahhh i was hoping you would eventually get to this.
So what you are technically saying is that the stances god has in the old testament vs the new testament are the same because "God has NEVER changed." Even though you just said the teaching by Jesus in the New Testament are more acceptable. Even though Christians believe that Jesus is the son, yet at the same time is God? So technically you are saying that these 2 very different stances on issues (accept homosexuals vs kill homosexuals) are coming from the same mind? So if Christians have the feeling that the Old Testament is "not under grace" or something, then how come so many Christians use it as a method to explain their position on homosexuality, laws, creation...?
thats right God has NEVER changed. the new testament does not make the old testament invalid. the people at the time could not live up to Gods standards, they constantly broke the law and where cleansed only once a year when the high priest would offer a blood sacrifice for the peoples sins. they got so bad though that God destroyed the evil ones in the flood and saved the only few righteous...noah and family. He gave the new testament (grace and mercy) as an easier way for us because we could not live up to the law. and yes Jesus is the son of God and God Himself. He needed a way to show us (humanity) how to live and He needed to provide us with salvation so He came down as Jesus and lived a pure sin free life, taught us the easier dumbed down version so we could live and understand it, and then offered Himself as a pure blood sacrifice for our sins so we could obtain forgiveness always. thats why Jesus said, " none may come to the Father except through Me" john 14:6-9. and Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved." acts 4:12. Jesus also said, " I and My Father are ONE" john 10:30. He made the way easier for us.

you say:

and i say to you the point again that there are few "true" christians. Jesus taught us that we are to love all no matter what, that we are to pray for are enemies and love them, and that HE alone has the right to judge. we are not to embrace the ways of the world ( homosexuality, fornication, theft, ect...) but to embrace the person who does these and teach them of forgiveness and what is needed for them to obtain salvation. as far as the old testament goes...(laws and creation) they offer us a guideline to live by(10 comandments) and give us a history on our ancestors and how the world came about by God( creation ). hope this helps. God bless
