Mistakes have consequences. Sometimes you don’t even realize you are making a mistake in the moment, it seems like the right thing to do, but there are still consequences. And sometimes, if you are Abram and Sarai, you make mistakes that change the course of world history and the consequences of your actions will continue to be felt for millennia.
The Master's Table 
The echoes of choices I live with every day even as grace restores.
Yes, let’s make no mistake. God’s plan well ahead of time was to deal with those consequences. One of the lessons of Genesis 15 is that God plays the long game. It is a great comfort to me that even in my foolishness I cannot derail the plan of God.
