The single greatest tool for evangelism that we possess is doing what is right, how we live, that which is holy in this way it will silence our critics. In this way, if we live irreprovably our enemy has no way to fasten his teeth on us thus they will also may glorify God by seeing us living a holy life.
Beloved, I urge you as sojourners and exiles to abstain from the passions of the flesh, which wage war against your soul. Keep your conduct among the Gentiles honorable, so that when they speak against you as evildoers, they may see your good deeds and glorify God on the day of visitation.
Be subject for the Lord’s sake to every human institution, whether it be to the emperor as supreme, or to governors as sent by him to punish those who do evil and to praise those who do good. For this is the will of God, that by doing good you should put to silence the ignorance of foolish people. Live as people who are free, not using your freedom as a cover-up for evil, but living as servants of God. Honor everyone. Love the brotherhood. Fear God. Honor the emperor.
Servants, be subject to your masters with all respect, not only to the good and gentle but also to the unjust. For this is a gracious thing, when, mindful of God, one endures sorrows while suffering unjustly. For what credit is it if, when you sin and are beaten for it, you endure? But if when you do good and suffer for it you endure, this is a gracious thing in the sight of God.
– 1 Peter 2:11-20
Likewise, wives, be subject to your own husbands, so that even if some do not obey the word, they may be won without a word by the conduct of their wives, when they see your respectful and pure conduct. Do not let your adorning be external—the braiding of hair and the putting on of gold jewelry, or the clothing you wear— but let your adorning be the hidden person of the heart with the imperishable beauty of a gentle and quiet spirit, which in God’s sight is very precious. For this is how the holy women who hoped in God used to adorn themselves, by submitting to their own husbands, as Sarah obeyed Abraham, calling him lord. And you are her children, if you do good and do not fear anything that is frightening.
Likewise, husbands, live with your wives in an understanding way, showing honor to the woman as the weaker vessel, since they are heirs with you[a] of the grace of life, so that your prayers may not be hindered.
– 1 Peter 3:1-7
