1 Peter 2:12 having your conduct honourable among the Gentiles, that when they speak against you as evildoers, they may, by your good works which they observe, glorify God in the day of visitation.
As Christians we are called to live an honest life thereby being able to obey the commandments that God has given us as much as possible.
Just the fact that we are Christians will bring up feelings against us and some will dare to speak evil against us in public.
We should not let those people get us down but rather continue demonstrating that we stand up for Christ and when the time comes our works will help to convince them that Christ is real.
