Ephesians 6:17 Take the helmet of salvation and the sword of the Spirit, which is the word of God.
Once we accept Christ into our lives and allow Him control rather than fighting Him every step, we will find what it is like to want to share the Gospel as Jesus did.
When a warrior goes out to war, they make sure they have the right clothes and equipment to give them the best chance at staying safe on the battle field.
We too need to make sure we have the best chance on our battlefield by making sure we are prepared too.
God does not want us to lose, He wants us to win!
