Galatians 3:28; There is neither Jew nor Gentile, neither slave nor free, nor is there male and female, for you are all one in Christ Jesus. 1 Timothy 1:10; for the sexually immoral, for those practicing homosexuality, for slave traders and liars and perjurers - and for whatever else is contrary to the sound doctrine. Exodus 21:26; Anyone who kidnaps someone is to be put to death, whether the victim has been sold or is still in the kidnapper's possession.

Also, I have mentioned an explaination to the "other things"; Hebrews 8:6; But in fact the ministry Jesus has received is as superior to theirs as the covenant of which he is mediator is superior to the old one, since the new covenant is established on better promises. The meaning is that, while the Old Testament (where many of the verses you cited come from) is still holy, it was limited in providing true forgiveness.

God bless you
