How do we know that believers are called to proclaim Christ?

In scripture, the burden of a believer is fundamentally to proclaim the message of Jesus Christ. This calling, represented by the word 'burden' in scripture, is not a mere obligation but a weighty responsibility bestowed by God. As noted in 1 Corinthians 9, 'necessity is laid upon me' signifies that Paul understood his calling to preach Christ as an essential task. Similarly, Habakkuk's message was one of divine revelation aimed at pointing people to God, indicating that every believer shares a unique duty to declare Christ and His gospel to the world.
