'Anyone' in the Bible

Do you not know that when you continually offer yourselves to someone to do his will, you are the slaves of the one whom you obey, either [slaves] of sin, which leads to death, or of obedience, which leads to righteousness (right standing with God)?

However, you are not [living] in the flesh [controlled by the sinful nature] but in the Spirit, if in fact the Spirit of God lives in you [directing and guiding you]. But if anyone does not have the Spirit of Christ, he does not belong to Him [and is not a child of God].

I know and am convinced [as one] in the Lord Jesus that nothing is unclean [ritually defiled, and unholy] in itself; but [nonetheless] it is unclean to anyone who thinks it is unclean.

Do not, for the sake of food, tear down the work of God. All things indeed are [ceremonially] clean, but they are wrong for the person who eats and offends [another’s conscience in the process].
