Be strong in the Lord and in the power of his might. Put on the whole armor of God, that you may be able to stand against the wiles of the devil. Ephesians 6:10-11.
There are many directives God has given us for protection while we are here on earth. In Ephesians, He is instructing us to put on HIS armor, so we are under HIS full protection. This is something we can’t do by ourselves. If we are following God closely and being a strong voice for God, then we are becoming a threat to the devil. In turn, we need to be protected to do God’s work for the Kingdom.
