The mandate of preaching the word is a responsibility of every Christian. Ministries which do not understand this often time cannot have influence on a generation.
The verse shows us that the believers who were scattered due to the persecution of the church begun to preach the gospel. This shows us that the first church was a missionary based church, they preached as a matter of mandate and not campaign.
Until every believer understands this mindset, the goal of transforming nations takes long. Find a part in reaching out to a soul in this gospel. Teach yourself never to stand before God without carrying along a person for ministry.
Heavenly Father, we thank you for giving us the mandate for preaching the gospel to our nation. Give us boldness today, that with boldness the gospel is proclaimed. AMEN
