The Word of God is our weapon to use against our enemy, the devil.
New Living Translation
I have hidden your word in my heart that I might not sin against you.
I will delight in your decrees and not forget your word.
Then I can answer those who taunt me, for I trust in your word.
May all who fear you find in me a cause for joy,
for I have put my hope in your word.
I have refused to walk on any evil path,
so that I may remain obedient to your word.
Your word is a lamp to guide my feet and a light for my path.
The teaching of your word gives light, so even the simple can understand.
Guide my steps by your word, so I will not be overcome by evil.
For the word of God is alive and powerful. It is sharper than the sharpest two-edged sword, cutting between soul and spirit, between joint and marrow. It exposes our innermost thoughts and desires.
Therefore, put on every piece of God’s armor so you will be able to resist the enemy in the time of evil. Then after the battle you will still be standing firm.
1 Peter 5:8
Stay alert! Watch out for your great enemy, the devil. He prowls around like a roaring lion, looking for someone to devour.
