For it is God’s will that by doing good you should silence the ignorant talk of foolish people. Live as free people, but do not use your freedom as a cover-up for evil; live as God’s slaves.1 Peter 2:15-16 (NIV)
We all like to do good, even when in some circumstances that can be incredibly difficult to do, when those around us are non-believers.
However in those difficult circumstances we must continue to do God’s will, as that is what God has directed us to do. Facing difficult circumstances and difficult people is never easy, but when we trust God, we can be assured that He will always be by our side, and will help and guide us through any difficult times.
So continue to do good, and continue trusting God, and He will help you talk to those who would consider your faith foolishness.
