When we are surrounded by people who don't believe in God, are critical of Christianity, or even hostile to our faith, it can be very difficult to even admit that we believe what we believe. We fear their rejection, their attacks, their influence over others we care about, and whatever else they might do to us. When God calls Ezekiel to be a prophet though, God makes it very clear who he should fear, and it's not his audience.
Fear God, not the people we are called to reach.
Ezekiel 2:3-8 & 3:17-21
