If you will be at peace with God and man, Evans, you need to confess and forsake your sins. You need to renounce the Devil and his messengers, the false teachers of Nigeria. You have received devils because you opened yourself to the powers of darkness. Your heart hasn't been right with God and you haven't been seeking the Truth.
Those messengers who visited you aren't the issue. You are. They would have had no access to your heart unless you had fault. Corruption is always from within. Satan came and found something in you. You are not just a victim, but the offender, the cause of your own problems. Read Victims and Perpetrators
Truth will make you free (John 8:32, 36). God will not turn anyone away that asks for what is right and true (Matthew 7:11; Luke 11:13). Read at our site continuously and ask God to lead and give you understanding, and to deliver you from delusion and darkness. Confess your sins to Him and ask Him to reveal secret sins.
