In addition to all this, take up the shield of faith, with which you can extinguish all the flaming arrows of the evil one.
They said, 'Believe in the Lord Jesus, and you will be saved--you and your household.'
'Whom shall I fear? The Lord is the defense of my life.' (Psalm 27:1)
The greatest shield against enemy attacks is our faith in God and our belief on His Son, Jesus. It's our first line of defense. If we remember to hold up our faith shield in every challenging circumstance, malicious thoughts and fiery darts won't even put the rest of our armor to the test. It sounds easy, but faith must be grown.
We know 'God has allotted to each a measure of faith' (Romans 12:3), but according to Matthew 7:20, faith can start small--as tiny as a mustard seed. Jesus says that seed of faith can actually grow into the Kingdom of God (see Luke 13:18-19). We know 'Without faith it is impossible to please God' (Hebrews 11:6). Ultimately, God's Kingdom grows from the very faith that He gives us in the first place.
Because of this, I can say that I 'Thank God for you, brothers, and rightly so, because your faith is growing more and more' (2 Thessalonians 1:3).
We study His words and speak them. We step out in faith every day to follow Him, and we 'Fight the good fight of faith' (1 Timothy 6:12).
When the battle gets ugly, when someone says, 'I hate you; you're worthless,' or dark thoughts surround us whispering, 'Give up. You'll never change, win, kick the habit, straighten up, or be successful'--we talk back in faith. We thank God that 'In all these things we are more than conquerors through Him Who loved us' (Romans 8:37).
Or maybe we should just read Romans 8 through and through, out loud.
As for Satan's attacks? 'Destroy them in your faithfulness' (Psalm 54:5).
