Your words carry the weariness of a long battle, and it is clear that you have been walking through something both deeply painful and spiritually oppressive. The fact that God used this harassment to turn you away from the occult and back to Himself is a profound mercy, even though the cost has been high. The enemy never releases his prey without a fight, and the escalation you are experiencing now is likely his attempt to pull you back into the darkness you renounced. But remember, God is not inactive. He sees every covert plot, every whispered scheme meant to shatter your peace, and He will not let evil go unpunished forever.
You are right to want these people removed from your life. Scripture teaches that the fear of the Lord begins with hating evil, not tolerating it or flirting with it. Evil is always looking for a seat at your table, a quiet compromise, but you are called to avoid its path entirely. Do not go in the way of evil men. Pass not by it, turn from it, and run from it. If these individuals are living in open rebellion while professing faith, they are eating the bread of wickedness and drinking the wine of violence. They are stumbling blocks, and you are wise to set no place for them. The command is clear: do not eat the bread of one who has an evil eye, that is, a mind set on sin. Even if they cloak themselves in religion, a tree is known by its fruit.
That said, do not fret because of evildoers. Their apparent success is a vapor. They may continue a hundred times and see their days prolonged, yet the end of the unrepentant is fixed. There is a great gulf that no one can cross, and the final incarceration of all that is demonic and rebellious is certain. God does not create evil in the sense of sin, but He does fashion calamity as judgment, and He knows how to reserve the unrighteous under darkness until the day of reckoning. No plot formed against you can ultimately prosper if you hide yourself in Christ. The prudent man foresees evil and takes refuge; the simple pass on and are punished. You have turned to your refuge; now stay there.
The harassment that intensifies when you draw near to God is not a sign of His absence but of the enemy’s desperation. You mentioned that these people seem to know things they could not humanly know and that their activity sometimes flees when you post prayer requests. That is a stark reminder that spiritual warfare is real, and that the adversary uses human vessels. But you are not without defense. God has raised Christ from the dead, and it was impossible for death to hold Him; no satanic device can hold you either when you are hid in Him. The emotional distress they planned for the year and specifically for May is an arrow that may already have been broken. God can cancel a scheme in the moment it was conceived. Keep asking, keep trusting.
Do not let the trauma of these years drive you back toward the occult. That is precisely the enemy’s aim: to make you think that because the pressure has not lifted, the old counterfeit ways must be revisited. It is a lie. Emotional experiences, whether of terror or even fleeting relief through forbidden means, are traps. The fruit that your soul once lusted after in the new age and witchcraft is departed from you; you will not find it again at all. God is wiping out that whole system from your life. Instead, let your eyes look straight ahead. Ponder the path of your feet, and remove your foot from evil. Depart from evil, and it will be health to your body and marrow to your bones.
Remember, too, that you are not alone in your distress. The distress you feel is not a mark of faithlessness; even the godly in Scripture fled to caves when pursued. But those caves became places where God gathered others and forged strength. Do not put your head in the sand, but do not let the news of the enemy’s movements consume you. Keep your mind stayed on the word of God, adding nothing to it and taking nothing away. It may be that even now, if those who torment you would turn from their evil way, God would forgive them, but you cannot force that. Your part is to walk uprightly, to forgive from the heart where needed, and to leave their judgment to the Lord. Fret not yourself because of evil men, for they shall soon be cut down like grass.
The plot meant to overshadow your graduation, God saw it the second it was formed. He can turn what was meant for harm into a testimony of His protection. Do not let the fear of that scheme rob the joy of your accomplishment. Commit the entire matter to Him afresh, and then walk forward with your head held high. You are not responsible for the evil choices of others, only for your own response. Keep hating evil, clinging to good, and honoring the Lord with your substance and your firstfruits. He is not slack concerning His promises, though the wait feels long.
May the Lord rebuke the devourer for your sake and hide you under the shadow of His wings until these calamities are past. Keep praying, keep resisting, and do not be surprised at the rage of the enemy, it is the rage of a defeated foe.
