The truth shall set us free only if we apply it with wisdom. Most of the time we fight the wrong battle, we fight those we love in the name of Jesus. Don’t allow yourself to be a pawn in his chessboard. You are the missing piece in his puzzle. He’s got the plan in place you are the only one that can make it successful, he will use the truth to fight you. Be alert at all times.
Introspect and evaluate your actions and see if you didn’t support his plan. 1 Peter 5:8-9 Be sober, be vigilant; because your adversary the devil walks about like a roaring lion, seeking whom he may devour. Resist him, steadfast in the faith, knowing that the same sufferings are experienced by your brotherhood in the world. The main aim of him attacking a union is to destroy it. What you are experiencing, your partner is experiencing in a different way but all work together for him. When he challenges your marriage, he can make one to be stubborn and allows you to play your part, he knows you’ll use the truth to judge the situation, in your truth you comply with him by fighting the spiritually inflicted partner.
He knows how Christians thinks, he’s been one of us. Matthew 16:23 But He turned and said to Peter, “Get behind Me, Satan! You are an offense to Me, for you are not mindful of the things of God, but the things of men.” Peter only knew the normal human behavior and responded the normal way a caring friend would do but Jesus realized that Satan has inflicted him. He dealt with the spirit behind the confusion not the person.
Your brother might still be in sin but he is not a sinner. Remember that God waited for you also. Don’t use what you see to make judgement. Satan is like a thief, he studies his subject and knows the strength and weaknesses of his opponents. He doesn’t just attack a person without facts. He knows even to use the truth to fight us. Job 1:9-10 Satan replied to the LORD, “Yes, but Job has good reason to fear God. You have always put a wall of protection around him and his home and his property. You have made him prosper in everything he does. Look how rich he is! God has not left us to be vulnerable, the Holy Spirit is there to guide us. He speak through a His Word and gives us wisdom. Be sensitive and obedient to Him as He speaks. Mark 13:11 But when they arrest you and deliver you up, do not worry beforehand, or premeditate what you will speak. But whatever is given you in that hour, speak that; for it is not you who speak, but the Holy Spirit.
Most of the time we know when we acted in an unjust way to others, because in any situation, He is always speaking. Jesus said “It is written” What is the scripture advising you to today that you are refusing? Check yourself.
