When dealing with strongholds

“For though we walk in the flesh, we are not waging war according to the flesh. For the weapons of our warfare are not of the flesh but have divine power to destroy strongholds. We destroy arguments and every lofty opinion raised against the knowledge of God, and take every thought captive to obey Christ.” (2 Cor. 10:3-5 ESV)

Take up the whole armor of God

“Therefore take up the whole armor of God, that you may be able to withstand in the evil day, and having done all, to stand firm. Stand therefore, having fastened on the belt of truth, and having put on the breastplate of righteousness, and, as shoes for your feet, having put on the readiness given by the gospel of peace. In all circumstances take up the shield of faith, with which you can extinguish all the flaming darts of the evil one; and take the helmet of salvation, and the sword of the Spirit, which is the word of God, praying at all times in the Spirit, with all prayer and supplication. To that end, keep alert with all perseverance, making supplication for all the saints.” (Eph. 6:13-18 ESV)

God is your stronghold 

“The Lord is good, a strong hold in the day of trouble; and he knoweth them that trust in him.” (Nahum 1:7 KJV)

Therefore…

“So if the Son sets you free, you will be free indeed.” (John 8:36 ESV)

Quote: 

“Nothing paralyzes our lives like the attitude that things can never change. We need to remind ourselves that God can change things. Outlook determines outcome. If we see only the problems, we will be defeated; but if we see the possibilities in the problems, we can have victory.” - Warren Wiersbe
