You might have heard a million times by now that everyone is sinful, and that sin is bad because it is a rejection of God, either in omission or commission. However, if we Christians accept Christ as our savior and God made us new again, then why do we keep sinning?
"I do not understand what I do. For what I want to do I do not do, but what I hate I do."
-Romans 7:15
Sin is rooted in the belief that there is something out there greater than God. God is, of course, the greatest thing anyone can have, but Satan is very good at tempting us and making us believe that there is something greater than God out there. But if God hates it so much and if it's such a bad thing to do, then why do we keep doing it?
The thing about sin is that it feels good to do. If sin was painful to do, then nobody would want to sin. But the fact is that it is enjoyable at the time. This is because sin plays with our desires and turns them into something that is not good. For example, sex is a beautiful thing, the highest expression of love that a husband can give to his wife. However, Satan took God's design and twisted it in our minds to make us think that it's a good thing to do. He eggs us on by telling us that it feels good. And yes, sex is supposed to feel good. It's supposed to be enjoyable. If it wasn't enjoyable, then why would you save it for someone that you love? However, the point here is that twisted desires make us want to keep sinning.
So how are we supposed to fight temptation and sin? It's simple to say but hard to do. Stand firm with God. Let God be God in you life, let God take control. God knows what's best for you and what isn't good for you, and He knows what it's like to be tempted, for Jesus was tempted as well. And if you feel like the temptations in your life are too big, then know this. God will never let you be tempted more than you can bear. You are strong enough for this, you just have to trust God. Remember, sinning is a matter of choice between God and your desires.
Now, will we ever be free from sin? Yes, when we are in Heaven with God. However, here on earth, it is impossible to be without it, simply because we are human.
But that, ladies and gentlemen, is exactly what Jesus has done for us. He has separated us from our sins as far the east is from the west.
Then why is it necessary to be a better person? Because the God fearing life is the best possible life, and that's exactly what God guides us toward. The best life, with God.
