We will face battles in our lives and what we are armed with will determine our outcome. Our first realization is that we wrestle not against flesh and blood but against principalities.
People wanted to equip David with battle outfits that didn’t fit his fight. He knew what God had equipped with a sling and picked out 5 smooth stones.
The New Testament has equipped us with the word to battle the principalities. I have scripture cards that have become my stones when I’m facing situations. I recall what his word says in that circumstance and declare his word for it in faith. I understand the battle belongs to the Lord.
