The weapons of your warfare are not physical weapons of flesh and blood, but they are mighty before God for the overthrow and destruction of strongholds. Refute arguments and theories and reasonings and every proud and lofty thing that sets itself up against the true knowledge of God; and lead every thought and purpose away captive into the obedience of Christ (II Corinthians 10:4,5). Speak up against those things that are not truth and declare the truth of God.
For you belong to Him, and will defeat and overcome the agents of the antichrist, because He Who lives in you is greater than he who is in the world (I John 4:4). So trust God. Lean on, rely on, and be confident in Him. You will not be put to shame or your hope be disappointed; for He will not let your enemies triumph over you (Psalm 25:2).
Strive to be one who does not offend in speech, for when you're able to do so, your character will be fully developed, and you'll be able to control your whole body and to curb your entire nature (James 3:2). For this is the will of God, that you should be set apart for pure and holy living: that you should abstain and shrink from all sexual vice. That you should know how to control and manage your own body in purity and honor (I Thessalonians 4:3,4).
And, then when you find others who are overtaken in misconduct or sin by any sort, you who are responsive and controlled by the Holy Spirit should set him right and restore and reinstate him, without any sense of superiority and with all gentleness, keeping an attentive eye on yourself lest you should be tempted also (Galatians 6:1,2).
Wisdom is a defense even as money is a defense,
but the excellency of knowledge
is that wisdom shields and preserves
the life of him who has it (Ecclesiastes 7:12).
God has called you an overcomer....He will help you overcome your fears, your faults, your enemies. Believe in Him, rely on Him, study His Word, the Bible. Ask Him to show you Himself. Then ask Him to show you who you are in Him. He will open your eyes to the truth. He will help you overcome and be His ambassador here on earth, as you become His hands, His feet, and His mouth, and help bring deliverance to others, as well!
