The devil is very bold. His tactics are always the same. He will always want to challenge you. You are sport for him.
Defiance is a clear act of rebellion.
Every act of defiance by satan should be met by an onslaught challenge by you. T here must come a time and place in your Christian walk where you are filled with so much confidence in your Lord, your God, where you fear nothing. It is really unneccessary. You must trust. The Word of the Lord is tested and tried.
