So many people do not like the truth of the Living God, and so make a god in their own image, how they want god to be. They despise Christ's sacrifice, so they make a god who will save anyone who is right in his own eyes. They scorn the holiness of the Lord, so they make a god who will save anyone and everyone. And so on. It was sad and destructive for Rachel to bring her idolatry to the promised land.
All idolatry is destructive, and leads to death.
We must be careful to not be like Rachel and try to enter the promised land with luggage full of the idols of the world. John Calvin, Commentary on Genesis , Vol. A Devotional Commentary , pg.
