Jeremiah was called by God to be a prophet despite being young, naturally timid, and lacking in eloquence. He was called to deliver messages of judgment to Judah during a time of great corruption and idolatry. Jeremiah struggled with this calling, as he was more inclined towards delivering messages of God's mercy. However, God equipped Jeremiah and transformed his natural weaknesses through empowering him with strength and making him bold in delivering his messages. Jeremiah provides an example of how God often chooses unlikely people to accomplish great things through relying on divine strength rather than human ability.
