Seven Deadly Sins
There are many many different sins not listed here; however, many of these great sins, like murder, adultery, stealing, etcetera have root causes, like pride. Pride was the devil's great sin, as he wanted to be like God, and rebelled. There are seven basic kinds of sin that lead to all others, known as the Seven Deadly Sins. It takes heroic virtue in most cases to overcome these.
Most of us are afflicted greatly with at least one or two of these. Once you give in to one of these sins, the spirits of the other six will be only too glad to come into your soul also. All of these sins will lead you directly to hell. 1 John 2:16 - "For all that is in the world, sensual lust, enticement for the eyes, and a pretentious life, is not from the Father but is from the world."
In the above scripture, John talks about three basic types of sin - The lust of the flesh (gluttony, lust, sloth), lust of the eyes (greed) and the pride of life (pride, envy, anger). Overcoming these things should be our life's work.
