"proclaiming the Kingdom of God and teaching about the Lord Jesus Christ with all boldness and without hindrance." Acts 28:30, 31
Luke relays to his readers that Paul was proclaiming with all boldness and without hindrance both the Kingdom of God and the teaching of Jesus. And that is what we as Followers of Jesus should do as well. We don't "have to share." We "get to share" the Kingdom of God and the Gospel of Jesus. How much do you believe about your faith? Is your faith so real that you see people like God sees people? Do you believe that people who are separated from God will be separated forever in a place called hell? Do you believe that Jesus' death was sufficient payment for the penalty for your sin? If the answer to these questions is "yes," then why would we not share this message with boldness? When you believe something is true, you want others to know it too. Be bold. Ask Him to use your life and your lips as you share in the mission.
Who needs to hear this life-changing message of Jesus?
