And he brought them out and said, “Sirs, what must I do to be saved?” So they said, “Believe on the Lord Jesus Christ, and you will be saved, you and your household.”
Acts 16:30‭-‬31 NKJV

“…that whoever believes in Him should not perish but have eternal life. For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life. For God did not send His Son into the world to condemn the world, but that the world through Him might be saved. “He who believes in Him is not condemned; but he who does not believe is condemned already, because he has not believed in the name of the only begotten Son of God. And this is the condemnation, that the light has come into the world, and men loved darkness rather than light, because their deeds were evil. For everyone practicing evil hates the light and does not come to the light, lest his deeds should be exposed. But he who does the truth comes to the light, that his deeds may be clearly seen, that they have been done in God.” (John 3:15‭-‬21 NKJV).

“For when we were still without strength, in due time Christ died for the ungodly. For scarcely for a righteous man will one die; yet perhaps for a good man someone would even dare to die. But God demonstrates His own love toward us, in that while we were still sinners, Christ died for us. Much more then, having now been justified by His blood, we shall be saved from wrath through Him. For if when we were enemies we were reconciled to God through the death of His Son, much more, having been reconciled, we shall be saved by His life. And not only that, but we also rejoice in God through our Lord Jesus Christ, through whom we have now received the reconciliation.”(Romans 5:6‭-‬11 NKJV).

“This is the message which we have heard from Him and declare to you, that God is light and in Him is no darkness at all. If we say that we have fellowship with Him, and walk in darkness, we lie and do not practice the truth. But if we walk in the light as He is in the light, we have fellowship with one another, and the blood of Jesus Christ His Son cleanses us from all sin. If we say that we have no sin, we deceive ourselves, and the truth is not in us. If we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness. If we say that we have not sinned, we make Him a liar, and His word is not in us.” (I John 1:5‭-‬10 NKJV).

“Now to Him who is able to keep you from stumbling, And to present you faultless Before the presence of His glory with exceeding joy, To God our Savior, Who alone is wise, Be glory and majesty, Dominion and power, Both now and forever. Amen.”
[Jude 1:24‭-‬25 NKJV].

If you depend on man-made weapons to keep you safe or protect you as a Christian, then you don’t know and haven’t experienced the presence,protection, and power of God Almighty, Fear,doubt, hate, are enemies that you can’t fight with man made weapons. Listen to what God’s word says :

“For though we walk in the flesh, we do not war according to the flesh. For the weapons of our warfare are not carnal but mighty in God for pulling down strongholds, casting down arguments and every high thing that exalts itself against the knowledge of God, bringing every thought into captivity to the obedience of Christ,…”(II Corinthians 10:3‭-‬5 NKJV).

“Yea, though I walk through the valley of the shadow of death, I will fear no evil; For You are with me; Your rod and Your staff, they comfort me. You prepare a table before me in the presence of my enemies; You anoint my head with oil; My cup runs over. Surely goodness and mercy shall follow me All the days of my life; And I will dwell in the house of the Lord Forever.” (Psalms 23:4‭-‬6 NKJV).

“He who dwells in the secret place of the Most High Shall abide under the shadow of the Almighty. I will say of the Lord, “He is my refuge and my fortress; My God, in Him I will trust.” Surely He shall deliver you from the snare of the fowler And from the perilous pestilence. He shall cover you with His feathers, And under His wings you shall take refuge; His truth shall be your shield and buckler. You shall not be afraid of the terror by night, Nor of the arrow that flies by day, Nor of the pestilence that walks in darkness, Nor of the destruction that lays waste at noonday. A thousand may fall at your side, And ten thousand at your right hand; But it shall not come near you. Only with your eyes shall you look, And see the reward of the wicked. Because you have made the Lord, who is my refuge, Even the Most High, your dwelling place, No evil shall befall you, Nor shall any plague come near your dwelling; For He shall give His angels charge over you, To keep you in all your ways. In their hands they shall bear you up, Lest you dash your foot against a stone. You shall tread upon the lion and the cobra, The young lion and the serpent you shall trample underfoot. “Because he has set his love upon Me, therefore I will deliver him; I will set him on high, because he has known My name. He shall call upon Me, and I will answer him; I will be with him in trouble; I will deliver him and honor him.” (Psalms 91:1‭-‬15 NKJV).

“Finally, my brethren, be strong in the Lord and in the power of His might. Put on the whole armor of God, that you may be able to stand against the wiles of the devil. For we do not wrestle against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this age, against spiritual hosts of wickedness in the heavenly places. 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. Stand therefore, having girded your waist with truth, having put on the breastplate of righteousness, and having shod your feet with the preparation of the gospel of peace; above all, taking the shield of faith with which you will be able to quench all the fiery darts of the wicked one. And take the helmet of salvation, and the sword of the Spirit, which is the word of God; praying always with all prayer and supplication in the Spirit, being watchful to this end with all perseverance and supplication for all the saints—” (Ephesians 6:10‭-‬18 NKJV).

Christians are followers of Christ, let’s look at how Christ handled situations, without man-made weapons.

“But Jesus said to him, “Put your sword in its place, for all who take the sword will perish by the sword. Or do you think that I cannot now pray to My Father, and He will provide Me with more than twelve legions of angels?”
(Matthew 26:52‭-‬53 NKJV).

“Now to Him who is able to keep you from stumbling, And to present you faultless Before the presence of His glory with exceeding joy, To God our Savior, Who alone is wise, Be glory and majesty, Dominion and power, Both now and forever. Amen.”
[Jude 1:24‭-‬25 NKJV].
