A promise is always most treasured when you are down and out. When you are at your lowest, you cannot imagine happiness. That is why we need to have a mental image that gives us hope. Israel had been in exile when Jeremiah gave this promise from God. So I imagine that their mental image is the land which was promised to them in Joshua 1 – where God promises to bring them back to their homeland.
Abraham went to the land which God planned for him to go by leaving his country, his people, and his father’s household. It is a blessing that he responded to God with obedience. This story reminds us to do what God has told us with strong faith and full obedience. God never promised the absence of storms in our lives, but He did promise to walk with us through them.
