You follow God. You are building altars for his name. Everything is going well. You are feeling blessed which makes altar building easy. Then... you hit a wall. A famine. Work is not going well. There are tests for following God. All of a sudden the promises of God seem fuzzy. Then crisis. You are put in a situation to use your smarts, money, time, and power to avoid a potential game-ender. Or, while God may use those things, you could stop and trust Him. You stop and go to the Word and see again that he says he will keep you. You remember that He is faithful, so you can obey and watch as he deals with the consequences. That is our story in Genesis 12:10-20
