In Matthew 10, we learn that Jesus said to the twelve disciples before sending them out, "Everyone who acknowledges me before others I will acknowledge before my heavenly Father. But whoever denies me before others, I will deny before my heavenly Father." Fair enough. I should think that being too embarrassed to let others know that we have faith in him is basically denying him. Timidity is a sign that we have not given the Holy Spirit free rein yet. A timid Christian is an unfit one, for he cannot bear much fruit. Since the Lord always spoke the truth, we must take his words seriously. Not paying attention to the above-quoted sayings can bring about dire consequences.
