I get that. However, I am a sinner, so who the heck am I to judge others.
Although, those whom I KNOW don’t believe in Christ being the Son of God and refuse to do so, I simply dismiss.
Don’t know offhand the scripture in which He states to do so....I just remember it and do so.
Because of that, and because every human being's eternal destination is predetermined by eternity, we can work and study with unbelievers and retain a clean conscience.
