We sometimes live behind a “closed door” and we do not share our faith. Why do you think is it like that ? The only place we would be able to share our faith is on earth. God has called us to be light bearers and bring forth His word to His people. We can’t share our faith if we don’t speak to people. What is more important, God or you. Pray for boldness and courage.
Wait upon God and ask what is on His heart. You have no reason to be afraid, because the Lord your God is with you where ever you go .
Proclaim his name faithfully
