God makes promises that are too good to be fake, and we respond by faith.
14 “‘The days are coming,’ declares the Lord, ‘when I will fulfill the good promise I made to the people of Israel and Judah. 15 “‘In those days and at that time I will make a righteous Branch sprout from David’s line; he will do what is just and right in the land. 16 In those days Judah will be saved and Jerusalem will live in safety. This is the name by which it will be called: The Lord Our Righteous Savior.’
Jeremiah 33:14-16
