We are being sent forth to communicate what Jesus Christ means to us. The disciples used verbal proclamation, of what they had experienced and had seen. Our spoken words must be clear and understandable as we witness.
There will always be Nay Sayers who will criticize and find fault, but we are to not be swayed by the opinions of others.
Read the Bible as it tells truth and we will discover that life is not utopia, and often the Guidance of the Holy Spirit will make us and others uncomfortable.
