No weapon formed against you shall prosper. Isn't that great news! Isn't it good to know that no sickness, no circumstance, no problem that rises against you can successfully bring you down?
Some years ago, one of our friends was facing a lawsuit. He and I prayed together according to this scripture and agreed it was the final word in the situation, not the allegations against him. We stood in faith, believing that lawsuit had to fail.
Sure enough, when my friend went to court, they just couldn't beat him. He didn't win that case because of his keen and witty lawyers. He won because he was innocent and because he had believed that powerful promise of God.
Follow his example. When the devil attacks you in some area of your life, don't sit around crying and begging God to save you. Open up your Bible to Isaiah 54:17 instead. Remind yourself of what God has promised you. Use that promise to strengthen you against sin and every other evil work the devil would like to use to keep you bound.
Then establish yourself on it through prayer. Say, "Lord, I refuse to be afraid of this weapon the devil has brought against me because I know that according to Your Word, it cannot prosper. I trust You to protect me, and I thank You for it now. In Jesus' Name. Amen."
Don't let the powerhouse of God's protection go to waste. Put it to work in your life. It is your rightful heritage as a servant of the Lord.
