I keep having these very disturbing blasphemous thoughts concerning Jesus Christ and Him sinning. These thoughts bombard me out of nowhere. It is like war going on in my head. Please provide me with spiritual advice to help me regain peace.
Satan can attack us with all kinds of thoughts. We cannot stop thoughts from coming, but indeed we can fight them and prevent them from nesting in our head. Do not fight thoughts with thoughts; instead fight thoughts with the Word of God. St. Paul said, "For we do not wrestle against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this age, against spiritual hosts of wickedness in the heavenly places" (Eph 6:12). In order to be able to conquer this temptation you have to persist on praying and reading the Holy Bible and as St. Paul taught us, "Stand therefore, having girded your waist with truth, having put on the breastplate of righteousness, and having shod your feet with the preparation of the gospel of peace; above all, taking the shield of faith with which you will be able to quench all the fiery darts of the wicked one and take the helmet of salvation, and the sword of the Spirit, which is the word of God; praying always with all prayer and supplication in the Spirit, being watchful to this end with all perseverance and supplication for all the saints" (Eph 6:14-18). May God be with you and strengthen you through this trial.
