It will become easier the longer you do this. Get a good, easy to read translation like the New International Version and learn the New Testament for yourself. Also, buy the New Testament on cassette tape, so you can listen to it at various times throughout the day. A great time to listen to the Bible on cassette tape is when you go to bed at night. Listening to the word of God will not only feed you spiritually, but prevent lustful thoughts and imaginations from coming into your mind.
Trash belongs in the trash pile so get rid of it.
Also, don't go places where the devil will especially be able to tempt you. This means that places like the beach, public swimming pools, etc. must be avoided. Humble yourself before Him and ask for His help as you follow what He has already given us in the Holy Bible. Please read Rom.
