Rev 3:7-13
1) Many are fighting the enemy with no weapons - You need harps & slings 1 Sam 16:16-18, 17:40
2) The power of your testimony Rev 12
3) The anointing of God in you - You need to know the difference in Saul's armor (put on outside) and Samuel's anointing (on inside) 1 Sam 17
So many people want to put their armor on you so you can fight their fight.
Psalm 127
4) He broke for his son - loved him so much
