Sin acts like a boomerang ~ any sin committed will return to haunt you, causing regret. You can harden and choose to ignore it, but this is like sweeping things under the rug ~ you won't have your peace back. Sinning hurts God foremost, yourself, and others too. To sin to gain some momentary pleasure or satisfaction at the expense of others, risking losing your soul in the process ~ this is definitely not cool, to put it mildly. In conclusion, sin is not worth committing. Therefore, let's welcome the coming of Christ into our world, imparting the good news of saving us from sin once and for all. He is the only one who can wipe our spiritual record clean.
