Bible Verses on Spiritual Warfare

"Submit yourselves to God. Resist the devil, and he will flee from you." James 4:7

"You are from God, little children, and have overcome them; because greater is He who is in you than he who is in the world." 1 John 4:4

"For though we live in the world, we do not wage war as the world does. The weapons we fight with are not the weapons of the world. On the contrary, they have divine power to demolish strongholds. We demolish arguments and every pretension that sets itself up against the knowledge of God, and we take captive every thought to make it obedient to Christ." 2 Cor. 10:3-5
 
"Be self-controlled and alert. Your enemy the devil prowls around like a roaring lion looking for someone to devour. Resist him, standing firm in the faith." 1 Pet. 5:8-9

"No weapon that is formed against you will prosper; and every tongue that accuses you in judgment you will condemn. This is the heritage of the servants of the Lord, and their vindication is from Me," declares the Lord." Is. 54:17

The Value of Prayer

Pray often, for prayer is a shield to the soul, a sacrifice to God, and a scourge for Satan.

– John Bunyan –

The one concern of the devil is to keep Christians from praying. He fears nothing from prayerless studies, prayerless work, and prayerless religion. He laughs at our toil, mocks at our wisdom, but trembles when we pray.

– Samuel Chadwick – 

If We Are Struggling in Prayer

If we are struggling in prayer it is because the wiles of the enemy are getting the upper hand, and we must look for the cause in our lack of discipline. There are some things we have not been strenuously practicing. We used to pray in the morning, do we now? We used to commune with God over the Bible, do we now? We used to be in contact with God wherever we went, are we now? Put on the whole armor of God and continuously practice, then the wiles of the devil cannot get you unaware.
