Abram’s father (at this point God hadn’t changed his name to Abraham) took his family and planned to move them to the land of Canaan. On the way, he stopped in Haran.
Terah took Abram his son and Lot the son of Haran, his grandson, and Sarai his daughter-in-law, his son Abram’s wife, and they went forth together from Ur of the Chaldeans to go into the land of Canaan, but when they came to Haran, they settled there. Genesis 11:31, emphasis mine
Later we learn that God tells Abram his descendants will own the land of Canaan: the Promised Land. Terah had the chance to live in the Promised Land, the land his descendants would live on and enjoy, but he never saw it. He never experienced the land of milk and honey because he settled. He was SO CLOSE. When Abram moved, the next sentence says he reached Canaan. I know it wasn’t as fast as reading the next sentence, but it doesn’t say that it took him a long time to get there.
The Bible doesn’t say why Terah gave up. Maybe the journey had taken a toll on him and he rested a bit in Haran and never left. Maybe he felt like, “This is good enough,” and never pursued anything better. Don’t do that! There are better things for you!
“I know the thoughts I think toward you,” says the LORD, “thoughts of good and not evil, to give you a future and a hope.” Jeremiah 29:11
This is a direct quote from God. There’s a future and a hope for you. You have a Promised Land of your own. I don’t know what that is, but you may. Don’t settle. Keep going until you reach it. Then praise God for bringing you there, and enjoy the blessings of your Promise.
