Angelo, I'm sorry I have been signed out I had some stuff to do.
I'm really happy you have told me all this because it's important that I know what you are going through. First of all you are not hopeless - far from it. You are greatly loved by God. There is nothing I repeat NOTHING that can separate you from God once you have given your life to Him (I believe you have done this going back over your posts) nor is there any sin too great to be forgiven - no NONE. Let's go through them:
1. We are all ashamed of ourselves at some time or another, we all break God's commandments, we cannot keep them because our fallen nature makes this impossible. Our fallen selves came about because of the original sin in the garden of Eden (Genesis) that is why Jesus had to die for us - God made a way for us, God is good. Because Jesus died for us we are instantly forgiven but that doesn't mean we should ever stop trying to not sin. It is a goal we work toward all our lives.
You blasphemed His name? Welcome to the club - I had been doing it for 53yrs - yes I used Jesus' name as a swear word, a curse word and God's name too. I have been forgiven as have you. The occult you gave up - Satan is trying to lure you back to "alternative" and possibly dangerous (certainly dangerous if it takes you away from God) cults/religions. Cast out the enemy in Jesus' name and he will flee from you.
You are 14 and you probably have raging hormones, yes sex and sexual acts will be constantly on your mind - it's your age! The point is you recognise that thinking this way is not in harmony with God's economy but you are not alone in your thoughts, it is so common I would say it's normal.
2. You build a relationship with God, it is OK to rage at him, He gets it, He understands because He created you. It's hard for all of us to "be good" and we all fail, some more than others but all of us at times. The key is to take it before God, we must confess our sins, He knows anyway lol. When we confess He forgives - every time.
3. OK this one I don't think you can do alone, I think you need to be prayed over in a church because I think the enemy is attacking you causing this anger and hatred - this is not of God and the fact that you were into an occult seems to confirm this. don't be concerned though I know of someone who had this problem, took this action and was instantly "cured". You will come away feeling at peace and greatly loved. Our God is a God of peace and tranquility not hatred or anger. Having a relationship with God will help you to know Him, what is of Him and what is of the enemy when He/it speaks to you so it's important you get into a relationship with God. You say your thoughts are like "supernatural"? That is exactly what they are!
4. Lying is another sin you must learn to control, you must want to stop this which has become habit. When you are about to lie stop yourself. Ask God to help you with this, you can even ask Him (silently) as you are about to lie. Just say something like "please help me".
5. Ah pornography rears it's ugly head again, this seems to be the leading sin among young Christian men. This sin can be defeated but again you must want that to happen. You can tackle this as in answer "4". With prayer some men manage to cast this sin aside instantly, with others it's a longer process. Keep working at it and don't beat yourself up when you fail. Keep praying about it.
6. No need to despair, God forgives you, God loves you each and every time. It's simple.
7. We glorify God because of what He has done, He deserves nothing less, He is worthy. He also loves you and wants to be in a relationship with you. He wants you free from the grip of the enemy.
8. You cannot be worrying about your parents right now. They are not the issue - you are. You cannot help them whilst you yourself are helpless. They know what they have to do to become saved. One day you will be an example to them and perhaps even witness to them but right now you need to focus on yourself. You need to look for a good Bible-believing church, fellowship with other Christians will help you more than you can know. you need to be in the company of those who can help nurture you and pray for you. I totally get your comments on reading the Bible, I struggled too particularly with the Old Testament. Get yourself a "Bible In A Year" the "Every Day With Jesus" Bible in a year is a good one. There are also online studies you can do with a daily reading portion accompanied by a pastor's summary - it's like having a friend decipher it for you. The Old Testament is hard going but the New Testament and in particular the Gospels (I particularly like John's Gospel) is enough for you to get a good solid foundation. when you find your church you can attend a Bible study group and study with others, helping each other and asking/answering the questions of others.
9. God had to be "harsh" on certain folks in the OT because of what they were doing. God did not want our world to become the way it has. These people were sinning on a large scale - even killing their own children. It was necessary.
10. God has 3 answers to prayer: 1. Yes with immediate effect. 2. No because it isn't for your benefit. You may not see this until later, look back and realise the "no" was a wise decision and beneficial to you. 2. Not yet. God's timing is always perfect, just because your prayers aren't answered with immediate effect it doesn't mean they won't be at a later stage. God will not forget your request.
I hope this will help you in some way but you need to act on these things, most especially you need to find a good church ASAP, read a Bible - the New Testament will do for now and pray often.
