1 Peter 3:15 "But sanctify the Lord God in your hearts, and always be ready to give a defense to everyone who asks you a reason for the hope that is in you, with meekness and fear."

1 Corinthians 10:4,5 "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."

Proverbs 26:4,5 "Do not answer a fool according to his folly, Lest you also be like him. Answer a fool according to his folly, Lest he be wise in his own eyes."

Colossians 2:8 "Beware lest anyone cheat you through philosophy and empty deceit, according to the tradition of men, according to the basic principles of the world, and not according to Christ."

Romans 1:16 "For I am not ashamed of the gospel of Christ, for it is the power of God to salvation for everyone who believes, for the Jew first and also for the Greek."

Romans 1:18 "For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who suppress the truth in unrighteousness,"

Romans 10:10-17 "For with the heart one believes unto righteousness, and with the mouth confession is made unto salvation. For the Scripture says, "Whoever believes on Him will not be put to shame." For there is no distinction between Jew and Greek, for the same Lord over all is rich to all who call upon Him. For "whoever calls on the name of the LORD shall be saved." How then shall they call on Him in whom they have not believed? And how shall they believe in Him of whom they have not heard? And how shall they hear without a preacher? And how shall they preach unless they are sent? As it is written: "How beautiful are the feet of those who preach the gospel of peace, Who bring glad tidings of good things!" But they have not all obeyed the gospel. For Isaiah says, "Lord, who has believed our report?" So then faith comes by hearing, and hearing by the word of God."

2 Timothy 3:16,17 "All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness, that the man of God may be complete, thoroughly equipped for every good work."

1 Corinthians 2:14 "But the natural man does not receive the things of the Spirit of God, for they are foolishness to him; nor can he know them, because they are spiritually discerned."

2 Corinthians 4:1-4 "Therefore, since we have this ministry, as we have received mercy, we do not lose heart. But we have renounced the hidden things of shame, not walking in craftiness nor handling the word of God deceitfully, but by manifestation of the truth commending ourselves to every man’s conscience in the sight of God. But even if our gospel is veiled, it is veiled to those who are perishing, whose minds the god of this age has blinded, who do not believe, lest the light of the gospel of the glory of Christ, who is the image of God, should shine on them."
