Fiery darts are lies. They often accuse. Revelation 12:10 named satan as, “…the accuser of our brethren…” Fiery darts are designed to attack our faith. In my experience they came in first person, such as “You are…, or you can’t…” followed by derogatory statements.”
We are to be diligent to guard our hearts (Proverbs 4:23) and to bring thoughts captive (2 Corinthians 10:5). When we aren’t, then lies will penetrate and seed into our hearts as we dialogue with them. They then become our own. From then on the battle is inside and no longer outside.
2 Timothy 2:14 says, “…not to strive about words to no profit, to the ruin of the hearers.” We can apply this to arguments within ourselves, or with others. There is no profit in it. It is fruitless, worthless, and an absolute empty activity. Daniel 7:25 says that he seeks to wear out the saints of the Most High through his pompous words.
Dialoguing with fiery darts is not only futile, but it emotionally, spiritually, and physically wears us down. Renounce the lies you have believed!
