Goliath’s sword had quite the history with David. It was the weapon used to dismember Goliath’s head from his body.
Goliath’s sword was also the weapon David used to cut a piece of clothing off of Saul while he slept in a cave.
David was able to make use of the victories God had previously given him. He was able to take from his past to help him in the present.
Have you made a habit of doing the same thing?
Bring to remembrance the times that God has provided for you. Write them down. Meditate on them.
Because going to your history with God will strengthen you as you walk in the here and now.
