How do we know the call to preach is true?

Knowing one is called to preach involves a profound burden for the truth and a willingness to speak it despite personal sacrifices. This calling is characterized by a love for the Gospel and a commitment to share it with others, trusting that God's Word will achieve its purpose (Isaiah 55:11). The true preacher’s motivation is to glorify Christ and not to seek a salary or recognition. As stated in 1 Corinthians 9:16, there is a necessity laid upon those called to preach, indicating that their calling is not a personal choice but a divine mandate that compels them forward.
