Jeremiah, Abigail, and Caleb are three characters in the Old Testament that were called by God to do mighty things in the Lord’s name. There is nothing particularly special about these people that God selected. However, they are essential because they committed their lives to the way of the Lord and remained faithful despite their circumstances. Jeremiah was obedient to God’s call, even though he did not feel talented. Abigail wasted no time to follow the Lord and was confident in her identity. Caleb held onto a promise from God for 40 years during war. Along with these biblical characters, we can believe God for big things.
