The war for the soul and thoughts of man is here. What is this war? Satan hates mankind and wants to destroy people. Many people mock this but this is the truth. Only in Christ people have the victory.
When I begin to lose this battle, I begin to fight it on my own. I need to take my thoughts to God. 2 Corinthians 10:4-5 says, "he 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."
Everyday I need to focus on the Bible and put the Bible in my heart by memorize the verses in my hearts. Psalm 119:9-11 says, "How can a young person stay on the path of purity? By living according to your word. I seek you with all my heart; do not let me stray from your commands. I have hidden your word in my heart that I might not sin against you."
