The mind is the battle ground. The devil has access to the mind as well as God. We are tempted through the mind. The devil will present wrong thoughts and then the Lord is right there to bring us good thoughts or suggest the right thing to do. We need to separate our thoughts. We need to cast out the wrong thoughts and only think on the good thoughts from God. The devil is like a persistent salesman. He will talk and talk at the door and if you are not careful he will get the door open and have his foot in it. If you give him any encouragement he will be sitting in your living room and have his wares all spread out before you. So we must not let the devil get past the door of our mind. Just tell him right off, "I am not interested." We think of the children of Israel in Egypt, when God told them to put the blood of the lamb on their doorposts one night, so their eldest son would be spared when the death angel passed over. Ex. 12:12,13. The blood on the door was the powerful warning to keep evil from the Israelites on that night when the Egyptians were visited and death was in every home. Just so, dear Grandson, the blood of Jesus on the door of our heart and mind will keep the devil from coming into our mind, sitting down and displaying all of his wares of evil. When tormenting thoughts, thoughts of fear, thoughts of unjust deeds of others done to you, thoughts of self-pity, anxiety, doubts, unforgiveness, mistrust of God, or evil of all kinds appear to take up your thoughts, just resist them and point to the blood on the door of your heart. Those thoughts will have to flee. Sometimes a person can think upon an unjustice done to him and it will grow bigger and bigger. The mistake is made by not resisting it in the beginning and forgiving the injustice. God's ways are right, if we will follow them. When bold and daring thoughts move in and are persistent, trying to fill every corner of our mind, we need to point to the blood. They have to leave. Bring the mind under subjection to the blood and think of good things. "And the peace of God, which passeth all understanding, shall keep your hearts and minds through Christ Jesus. Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, if there be any praise, think on these things." Phil. 4:7,8. Obedience to God's Word Be careful to obey the Word of God, and do not let others influence you to do wrong. Be strong and courageous to stand for right and truth. Dear Grandson, there will be many in the world who will sneer at you for your stand for right. Some will persecute you, but don't let this influence you to let down your standard from God of what is right. God expects us to obey Him. Others might try to make you think that the way they have figured it out is right, but still we must obey the Lord.
