Gossip is a sin. So is murder. Given the choice, I would rather you talk about me than kill me. From our perspective, sins of speech seem minor. But they are not.
Just because you don't see it or think about it doesn't mean the spiritual world doesn't exist. Your life is impacted by unseen realities every day. What would you see if God opened your eyes?
You chase the wrong things, and you will live for the wrong things. in the end, you will have wasted your life. Don't.
Maybe you have wondered why God doesn't seem to do what you ask him to do. The real question is why you don't seem to do what he asks you to do.
God is always about to do something new in your life. This means you must always be ready to let go of the way things have been in order to receive the new way things are going to be, Let Go. Let God.
You say that you got saved even though nothing actually changed. You say you believe in prayer but you don't really pray. You say you believe God exists, but you live every day as if he doesn't. No matter what you say, your life speaks for itself.
Just because you can do wrong without guilt or fear doesn't mean you're not guilty or that you have nothing to fear. No matter what, stay in touch with that uncomfortable ability to feel ashamed of yourself when you do wrong.
