What I speak to you quietly, announce loudly.
“What I say to you in the darkness, speak in the light; what you hear whispered, proclaim on the housetops.” Matthew 10:27
Jesus said this in the context of instructing His followers not to be afraid as He sent them out for ministry. He was telling them to be bold in their service of the Kingdom. He had just told them that they were being sent out as lambs in the midst of wolves. He had told them they would be beaten and arrested for identifying with Him. He said they would be betrayed even by family members.
He was about to tell them not to fear death. He was about to tell them they had to love him more than parents or siblings or children. He was about to tell them they had to be prepared to die for Him.
In this passage Jesus tells His followers that their public and bold acknowledgement of Him was tied to His public acknowledgement of them by Him before God the Father. It is interesting that in the book of Acts, the most frequently mentioned result of people being filled with the Holy Spirit is boldness. If we are ashamed of Him, He will be ashamed of us. Be bold in living for the Lord!
