What size is your shield?

"Stand your ground, putting on the belt of truth and the body armor of God’s righteousness. ¹⁵ For shoes, put on the peace that comes from the Good News so that you will be fully prepared. ¹⁶ In addition to all of these, hold up the shield of faith to stop the fiery arrows of the devil. ¹⁷ Put on salvation as your helmet, and take the sword of the Spirit, which is the word of God."- Ephesians 6: 14-17

Shield of Faith:
I have already talked about Faith. But since faith is so commonly talked about in the Bible, it must be very important.

What does a shield do for you?
wikipedia.com says that a shield is a type of personal armor that is used to counter off attacks.

In the ancient Roman days, the Roman army would take your measurements. How tall you were and how wide you were. They would custom make you a shield exactly to your measurements. The shield was one of your most important pieces of armor.

So if you have a shield of faith than you can readily fight off all of the wily works of the devil. It is essential for a Christian to take possession of all the pieces of armor. Especially the shield of faith.

Every one's shield dimensions are different. Just like every one's faith, our sizes are different. Depending on how much faith you have, the more you can do.
So just how much faith do you have?
