There is pressure from the humanists in our society to keep quiet about our faith. Leaders in society are criticized and attacked when they express biblical values which they are suppose to keep to themselves. This attitude is nothing new, as the society in the first century also attacked men of faith (cf. Acts 16:20-23). The sad reality is that some religious groups (that claim to be Christian), also have privatized faith in the sense that you are to have your own personal faith and keep it to yourself — do NOT share it with others and try to convince them that your view is right and theirs is wrong.
