How should Christians act towards atheists?
One example I have found is 2 Corinthians 6:14 [KJV].
Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness?
I believe this is saying not to marry atheists.
Are there any other instructions on how to behave towards unbelievers in the Bible?
