'Devoted' in the Bible

But even if we, or an angel from heaven, should preach to you a gospel contrary to that which we [originally] preached to you, let him be condemned to destruction!

As we have said before, so I now say again, if anyone is preaching to you a gospel different from that which you received [from us], let him be condemned to destruction!

For all who depend on the Law [seeking justification and salvation by obedience to the Law and the observance of rituals] are under a curse; for it is written, “Cursed (condemned to destruction) is everyone who does not abide by all things written in the book of the law, so as to practice them.”

These people who have been instructing you are devoted to you, but not in a good way. They want you to avoid me so that you will be devoted to them.

(Now it is always good to be devoted to a good cause, even when I am not with you.)
