I have a question regarding spiritual growth?

Yes it is normal. Remember that even Paul, the great apostle, said, "the good I would do, I do not; the evil I would not do, I do". Keep in prayer, keep in bible study, keep going to church, keep being in fellowship with other believers. We will not be released from the attacks of satan until we are off this planet. But greater is He that is in you, than he that is in the world. Have no fear; God has got you firmly in His hands.
