I am certainly glad that you wrote to us. I am so happy to hear that you have committed your life to Jesus Christ. About your questions. The Bible gives us the answer to that. This does not mean that God approves of our sin when we do sin.
Sin is a powerful thing.
Much more powerful then we are. He died for sin that we might be able to be delivered from all these aspects of sin. Paul the Apostle deals with many of your questions. I want to leave you with 2 other passages and also some comments. You are in a struggle now against the powers of darkness.
