The Armor of God is essential for winning the battle against spiritual forces of darkness. In Ephesians 6:10-20, the classic Scripture passage on the Armor of God, Paul writes about the various pieces of armor, and then concludes his description of the armor by asking the Ephesian Christians to pray for him that he would have boldness to preach.
In this way, we see that proclaiming the Word of God is also part of spiritual warfare. Paul talks about preaching in Ephesians 6:19-20, the concluding Scriptures on the Armor of God.
The following information was pulled from my sermon on Ephesians 6:19-20, which is a sermon about the Power of Preaching.
When it comes to preaching to others, we tend to think, “If only I had the opportunity to teach a bigger group, then I would prepare better, and teach with more conviction. But if it’s only five or six, why bother?”
Paul doesn’t care if it’s two or two thousand, he is going to preach with accuracy, and boldness because he knows that every person that comes his way has been sent by God.
