If you truly have believed by faith that "God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life" (that is believed Jesus died in your place to pay the penalty of your sins) and "if you confess with your mouth, "Jesus is Lord," and believe in your heart that God raised him from the dead, you will be saved" (John 3:16; Romans 10:9). For it is with your heart that you believe and are justified, and it is with your mouth that you confess and are saved (Romans 10:10). Have you done this? (Please answer this question for it will help me to help you). Do you believe Jesus is the only way to save you from the consequences of your sins? Remember, we are told that "the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord" ( Romans 6:23). Every sin that we do has such grave consequences that it produces total devastation. Only one sin by Adam and Eve threw all of creation into sin with its death, sickness, evil , sorrows etc. (this was not God doing this, but sin). God does not want us to sin, not because he is a harsh taskmaster, but because he knows the devastating consequences of sin including being separated from him.
God made us so he could share love and companionship with us. He loves us. He loves you and gave you a special purpose that can only be expressed through you being as he is (that is perfect) which is how a saved person is when in his Spirit. You do not even know how special you are yet, but I know that God created you for a wonderful purpose.
If you have asked God to be your savior and have done the above things the reason you are not experiencing the Holy Spirit is because of sin which you yourself say, " It's just that I overreact about the sins and some restrictions." Stubborn rebellion against God's way is you not God putting a block between you and him. Sin blocks us from God since God can't commune with sin since he is sinless. To further compound the problem, when you do this you are walking in your flesh which allows Satanic spirits to dominate you since this is their kingdom.
I must ask and I love you no matter how you answer, have you been involved in any kind of new age, psychic, demonic, witch, etc. type activities? If so, that is asking for this type of spirit activity. Also, just curious about the picture you have for your posts. What is the individual wearing? Is a ceremonial coat?
If you answer yes you are saved, then when you got saved you immediately began to have power over all evil spirits (for when living in God you live by God's power). Even if your mind vacillates between believing and trusting God to not believing and being against God, if saved you are still filled with God's Holy Spirit. God does not hold it against you if you are saved, but wants you to trust him to help you.
We were created in God's image. Every word creates, just as his words create. Proverbs 18:21 says, " The power of the tongue is life and death— those who love to talk will eat what it produces." Every word spoken, either from the from the flesh (which produces death) or from God's Spirit (which produces life) will cause consequences for not only the world, but ourselves. What we speak continues to create the world we are in. If you by faith speak and say I am free of all evil, believing God has freed you from evil, you will be speaking from God's Spirit because your words are confessing your trust in God and God's power (rather than your own) which frees you from the evil. If you say evil and don't trust in God, you are in your own power, or worse, Satan's power and you will reap the results of that.
Some good confessions for you to speak and believe are:
All my faith, hope, trust, and belief is in God (If you trust God with everything, he will take care of everything for you).
I have a hedge of protection around me that blocks all evil.
All my thoughts come from the mind of Christ.
I only believe good.
God always loves me.
God reveals the beauty of his ways to me.
I have power over all evil.
The Holy Spirit is alive in me always showing me the truth.
I can easily discern between God's voice and all other voices.
I always know God's truth.
My mind is always full of Godly thoughts, is always clear, and at peace.
All my thoughts come from God.
When you hear evil or confusing voices don't believe them, but focus and confess over them. Always say the confessions in the positive. Don't say I am never deceived. Rather say I always know the truth. Also, "God is not the author of confusion, but of peace" (1 Corinthians 14:33). Again, " For God hath not given us the spirit of fear; but of power, and of love, and of a sound mind (2 Timothy 1:7). If you are saved yet are confused by what you hear, it is not God talking to you. Every spirit or thought in your head that confuses you should be immediately ignored! Confusing thoughts are not helping you and lingering on them makes your situation worse (or forms the habit in you of believing the evil). When God speaks, however, you will be certain it is him and he always brings us the fruit of the Spirit when he speaks like love, joy, and peace and speaks from faith that good is true for you. Also don't dwell on why this is happening. That keeps you out of God's Spirit. Rather just believe that it isn't happening and focus on the confessions and that God only wants good for you. Power over evil comes from the belief that you are powerful over it and if saved you know you are, because you then have God's power since you live in him and he overcame all evil.
When someone gets saved they receive the Holy Spirit. The Holy Spirit is there to guide you and if you ask God for wisdom from the Holy Spirit he will give you for the bible says, “Ask and it will be given to you; seek and you will find; knock and the door will be opened to you. For everyone who asks receives; the one who seeks finds; and to the one who knocks, the door will be opened." (Matthew 7:7). This applies to salvation as well.
I would like to help you overcome your objections to God's ways. Are you willing to share what you believe are the restrictions that cause you to come against God. Maybe I can help you understand the beauty in God's thinking.
I pray that this helps you, that you turn fully to God, know his great and powerful love, come to understand his ways and live in the clarity of the mind of Christ.
