Father God,
In Jesus name, I ask You to give this brother of mine the faith and courage he needs to overcome this and every satanic attack. For You have not given us the spirit of fear, but of power, love, and a sound mind. (2Tim:1,7) Father, I'll now write this brother and give him briefly, what You have given to me.
Brother, first off, I want you to know that I believe you. There really are satanists out there with the same agenda as their fallen master. To steal, and to kill and to destroy. The enemy can appear in ruthless and fierce manifestations. I don't know why some of us see them and others don't. In street ministering, time and again people would want me to come to their homes to get rid of what was there. More and more people are getting hit with the reality of demons.
First, make sure that you have believed the Gospel. That you have repented of sin and received Jesus Christ as your living Lord and Savior. Second, believe every word in Scripture is true, including every promise to the believer. Know who you are in Christ! You HAVE AUTHORITY in JESUS NAME! Third, pray and memorize as much of the word as you can. Then, and this may seem hard and scary at first, stand up and step through the veil of fear the enemy sends at you. Command him, or them to leave in the Name of Jesus. They will! Submit yourself therefore to God, resist the devil and he must flee! People tend to forget the submit part. Don't! Confess the power of the precious shed blood of Jesus over your home and property. Get involved with Bible believing Christians. Find a Church to join. One that the Holy Spirit will lead you to. Get under the covering of believers' prayers and a loving Pastor. It can be so much easier for you. You may need much more help from those with spiritual discernment. If God is calling you to such a ministry, learn from those who are battle tested. Don't get on the job training by yourself. Read Ephesians six, when you get to the armor, see Christ in every piece. Read Lk{10,17-22. Read Mark:16,15-20. This is just a start! May the Holy Spirit lead you into all truth. For He is the Spirit of truth! Just don't be afraid! Walk in the peace and power of Our Lord Jesus.
Father, keep and strengthen this man according to Your mighty power. In Jesus name, Amen and Amen.
