How to Use Sword of Spirit

Do you remember the armor of God in Ephesians? (Posted at bottom of this blog) I always thought it was a great idea to put on this armor, but I really didn't get how to do it. Especially when told to fight with the Sword of the Spirit. I figured this must be the Holy Spirit, but how exactly do I use this to fight the wily schemes of the devil? While spending time with God the other day and being still, I heard God tell me how to do this. Begin by knowing what God says about you. If you do not know what God says specifically about you go to this blog post here. Once you have God's thoughts about yourself then write then out and say them daily so they become very familiar and agree with them. It is very powerful when we agree with what God says about us.
Anyway, God let me know that to use the Sword of the Spirit I was to test any thoughts that entered my head with the words God has told me about myself. Does this thought agree with what God says about me? If not, throw it out. Do not allow it to remain in the head. Do not perseverate or give it anymore air time. Repeat something God has told you, like, "I am God's treasure."
I really like this practical way of using the truths God has been telling me about me to battle against any gobbledegook satan is trying to sell me.

Ephesians 6:10-18

Contemporary English Version (CEV)

The Fight against Evil

10 Finally, let the mighty strength of the Lord make you strong. 11 Put on all the armor that God gives, so you can defend yourself against the devil’s tricks. 12 We are not fighting against humans. We are fighting against forces and authorities and against rulers of darkness and powers in the spiritual world. 13 So put on all the armor that God gives. Then when that evil day[a] comes, you will be able to defend yourself. And when the battle is over, you will still be standing firm.
14 Be ready! Let the truth be like a belt around your waist, and let God’s justice protect you like armor. 15 Your desire to tell the good news about peace should be like shoes on your feet. 16 Let your faith be like a shield, and you will be able to stop all the flaming arrows of the evil one.17 Let God’s saving power be like a helmet, and for a sword use God’s message that comes from the Spirit.
18 Never stop praying, especially for others. Always pray by the power of the Spirit. Stay alert and keep praying for God’s people.
