Who is there to harm you if you prove zealous for what is good? But even if you should suffer for the sake of righteousness, you are blessed. And do not fear their intimidation, and do not be troubled, but sanctify Christ as Lord in your hearts, always being ready to make a defense to everyone who asks you to give an account for the hope that is in you, yet with gentleness and reverence; and keep a good conscience so that in the thing in which you are slandered, those who revile your good behavior in Christ will be put to shame. For it is better, if God should will it so, that you suffer for doing what is right rather than for doing what is wrong. For Christ also died for sins once for all, the just for the unjust, so that He might bring us to God, having been put to death in the flesh, but made alive in the spirit; in which also He went and made proclamation to the spirits now in prison, who once were disobedient, when the patience of God kept waiting in the days of Noah, during the construction of the ark, in which a few, that is, eight persons, were brought safely through the water. 1 Peter 3:13–20, NASB
Genuine Christianity cannot coexist with any other religion. God has given us the tenets of our faith and they are mutually exclusive with the claims of all other religions. There can be no peace between them and true Christianity because once compromise has taken place here then what remains is something less and no longer true. We are called to live our lives in the flesh here in the temporal, but with entirely different motives than non-Christians. The confusion about this exists because what passes for Christianity, for the most part, in our time has been compromised. The world has been welcomed in in various ways at different levels and the professing Christians within are far more concerned about their temporal existence rather than obeying God in all things for His glory.
