The base of sin is man's desire to be God. A number of people have thought the base of sin is money.
This is off an incorrect scripture translation which states that "money is the root of all evil." The correct translation is that "money is the root of all kinds of evil."
This is actually important because man's desire to to God or to stand in opposition to God is much more fundamentally the sin of mankind. If is of course the first sin of mankind to believe that he knew better than God.
Sin always fundamentally is standing against God. Maybe it appears not the case, but the reality is that man's struggle with sin is always primarily against God.
One thing I always notice is that there is always grave hatred to Christianity. It is often at times irrational. Sometimes it cannot be explained.
Why do men hate Christians? Well they hate God and Christians proclaim God.
Actually Jesus promised that if we follow him people will hate us. So actually if people do not have us and we do not have opposition it is a bit doubtful we are following Jesus as we should.
People should not hate us for being sinful of course. The hatred the world should hate us for the love of God which we should show. Jesus came proclaiming the love of God and it quickly went down hill and for us it is often that way to a much lessor degree.
