There were warnings but also encouragement as I wrote in the post Of Most Importance is Jesus in Our Heart. We should be inspired to be a bold and persuasive witness through the Holy Spirit. Because of the Holy Spirit, we receive counsel at all times to help us and here is a video poem to inspire our day with this thought in mind: Blessings Throughout Each Hour.
Enable me to speak Your word with great boldness. Stretch out Your hand to heal and perform signs and wonders through the name of Jesus. – Acts 4:29-30
