If you claim to be a preacher of the Gospel of Christ, yet you are a coward, my friend, you do not worth the Bible with which you hold & profess to preach.
If you cannot speak truth to power, you are of all men, most miserable.
Think about Samuel, Elijah, Elisha, Jeremiah, John the Baptist etc, these were the real men & Prophets of the Most High God, who did exploits in their time, & days. And they were never afraid of saying the truth at every point in time. And, in many occasions, they did speaks at the expense of their lives.
