How are we supposed to act around our friends who aren't Christians because we can't be too spiritual around them, I mean we are still human.
I’m not sure what you mean by “too spiritual.” Certainly we must “walk in the light, as he [God] is in the light.” (1 John 1:7) We can live like Christ in the middle of unbelievers without having a “holier than thou” attitude. In fact, that is one method of preaching the truth to them. Peter recommended that method for wives of unbelieving husbands. “Likewise, ye wives, be in subjection to your own husbands; that, if any obey not the word, they also may without the word be won by the manner of life of the wives.” (1 Peter 3:1)
It may be that you will be ridiculed for your beliefs. As a non-drinker I often faced such ridicule in the Navy. But if you stand by your beliefs you will be respected more than if you act differently depending on whom you are with. Paul rebuked the apostle Peter for just such behavior. The account of that is in Galatians 2:11-14.
We should live and act the same with everyone. We should not do it in such a way that we are saying, “Look at me; I’m better than you.”
