But in your hearts revere Christ as Lord. Always be prepared to give an answer to everyone who asks you to give the reason for the hope that you have. But do this with gentleness and respect, keeping a clear conscience, so that those who speak maliciously against your good behavior in Christ may be ashamed of their slander.-1 Peter 3:15-16
Peter is the disciple who denied Jesus the first time he was asked if he was associated with Jesus, but the second time he was asked he gave a response that led to the salvation of about 3,000 people (Acts 2:1-41). What was the difference between the two? The first time Peter was not prepared to give an answer. He was not prepared to face the consequences for declaring that he was a follower of Jesus. However, after Pentecost Peter was filled with the Holy Spirit, which enabled him to stand up before the very same people who had shouted “crucify” about a mouth before and declare such a powerful message that 3,000 people were saved that day. This boldness and preparedness would follow Peter for the rest of his life. Until the day Peter died was always prepared to give anyone an answer for the reason for the hope that he had. You too should always be prepared to share the reason for the hope that you have. It is the primary mission that you have as a follower of Jesus. The world today is looking for hope and as Christians we have a hope. So go out and share your hope with the rest of the world.
