How do we know that God commands us to preach the gospel?

We know that God commands us to preach the gospel through various scriptural references that illustrate His desire for the message of salvation to be spread. In Matthew 28:19-20, known as the Great Commission, Jesus explicitly instructs His followers to make disciples of all nations, affirming the ongoing responsibility of the church to proclaim the gospel. Additionally, in Acts 4:19-20, the apostles demonstrated this command in practice when they declared, 'We cannot but speak the things which we have seen and heard.' This reflects a divine mandate that compels believers to share the message of Christ with urgency and faithfulness.
