@littlek,
True Christians obey the Word of God which plainly teaches to avoid Atheists.
Rom_16:17 Now I beseech you, brethren, mark them which cause divisions and offences contrary to the doctrine which ye have learned; and avoid them.
True Christians obey this verse. Nicolaitan Christians do not obey it, they choose to disobey this very and justify doing so, because they think they are going to get through to them, and change them to the light.
Those who draw close to God are they that God will draw close to.
You can't talk a person into drawing close to God, nor will you ever be able to convince an Atheist that there is a God, no not with a million words. let them alone, let them be. Today's Christians trying to reach an Atheist is doing nothing more then throwing pearls to swine, which Scriptures teaches us NOT to do.
Note: i am not suggesting we not answer them when they ask us a question, what i am saying, is we are not to engage them into conversations, or associate ourselves with them.
