Why should Christians preach the Gospel?

The call to preach the Gospel is rooted in the Great Commission found in Matthew 28:19-20, where Christ commands His disciples to go and make disciples of all nations. This command aligns with the sovereign will of God, who has determined to save a people through the folly of preaching. The story of Jonah underscores the importance of this mission; Jonah was sent specifically to preach to a people who had turned away from God. Despite his initial reluctance, Jonah's eventual obedience led to the repentance of Nineveh. In the same way, believers today are encouraged to share the Gospel because God has chosen to use their voices to call His elect to Himself. The preaching of the Gospel is therefore not merely a duty but an act of obedience to God's overarching plan of salvation.
