Some sins are described in the Bible__homosexuality, idolatry,etc.But some things SEEM wrong, but may not be mentioned specifically.Because I had this problem with some, and have heard others have it. Taking advantage of someone, and with intent to do so.We're to help others. I understand that. But I'm not talking about legitimate needs.I'm talking about someone who makes a lifestyle out of making their lives easier by finding others to do everything for them.Like, among many unsaved people I notice a tendency that, once they get to know someone a little,instead of just seeing the person as someone to be friendly with,right away the thought comes to mind,"this person can do this and that for me.they can be useful to me."Now, is it a sin to look to use someone to your advantage?I would think to a certain extent it is, because it involves selfishness,when you have a legitimate reason you can't do it at a certain time, and they don't work with you, they "push it",and don't take no for an answer.They want to "jump the line",if it's job related and you have other appointments first, they "don't take no for an answer"and try to "push themselves in."Also selfishness because you could do 5 things for them, and you need one thing one day, and they give every excuse why they don't want to{in other words, "one-sided"} Also, they sometimes "turn on you" if you can't comply.What I'm saying, everyone thinks the person turning down the favor is the selfish one,but I think the person ASKING FOR something can be selfish.Also, we're supposed to help, but if someone asks us for something against our principals, like if an unsaved husband asks a Christian neighbor,"My wife is away. Go tell my mistress I'm alone in the house"...come on.SOOO...is intentionally taking advantage of someone a sin, if it's done for the purposes of manipulation?I somehow think so.
