It's about not denying what we have seen and known. We have to get out of the habit of caution and the habit of being shy about the love of God that we ourselves have felt and seen. Most people aren't going to mock us. People are hungry for authentic experience. We don't have to say anything which is not real.
People respect honesty, just as they're offended by anything phony or second-hand.
If you feel God speaking quietly in your mind or in your heart, even if it seems as if God is speaking without words, then it's up to you to share it. Not just now, and not just this morning, but always. And listen, not just now, not just when you read the Bible, but all the time. God doesn't stop speaking when we walk out the door here. God speaks all the time, in the darkest situations and in the most difficult circumstances.
