Text: Deuteronomy 6:16-25
Introduction
Right after commanding Israel to love God with their whole heart, Moses turns to two very different scenarios: the temptation to test God, and the eventual moment when a child will ask what all these commands actually mean. Between these two moments lies a call to simply “do what is right and good in the Lord’s eyes.” This passage moves from a warning against doubting God’s provision, to a vision of how faith gets carried forward — not through abstract rules explained to children, but through an actual story told and retold.
I. Do Not Test God — Do What Is Right and Good (vv. 16-19)
Moses warns, “Do not put the Lord your God to the test as you did at Massah.” That reference points back to an earlier moment in the wilderness when Israel, thirsty and afraid, demanded proof of God’s presence — essentially forcing God to prove himself on their terms before they would trust him. Moses then gives a positive alternative: “Be sure to keep the commands of the Lord your God… Do what is right and good in the Lord’s eyes, so that it may go well with you.” Testing God demands proof before trust; doing what is right and good simply trusts and obeys, without first requiring God to perform on command.
This distinction matters for how we approach seasons of doubt or uncertainty. Testing God says, “Prove yourself to me first, and then I’ll trust you.” Doing what is right and good says, “I will walk faithfully, trusting that you are who you have already shown yourself to be.” The first posture keeps God on trial. The second posture actually rests in relationship with him.
Application Question: In my current uncertainty or doubt, am I demanding that God prove himself to me on my terms, or am I choosing to do what is right and good, trusting who he has already shown himself to be?
II. The Question Every Child Eventually Asks (vv. 20-23)
Moses then anticipates a moment that hasn’t happened yet: “In the future, when your son asks you, ‘What is the meaning of the stipulations, decrees and laws the Lord our God has commanded you?’ tell him: ‘We were slaves of Pharaoh in Egypt, but the Lord brought us out of Egypt with a mighty hand. Before our eyes the Lord sent signs and wonders — great and terrible — on Egypt and Pharaoh and his whole household. But he brought us out from there to bring us in and give us the land he promised on oath to our ancestors.’”
Notice how Moses instructs parents to answer. He doesn’t hand them a theological explanation of why the law is good in the abstract. He hands them a story — slavery, rescue, a mighty hand, a promise kept. When a child asks why we live the way we live, the most powerful answer isn’t a set of arguments; it’s the actual story of what God has done. Faith gets passed down most effectively not through explanation alone, but through narrative — a story a child can actually picture and remember.
Application Question: When the people around me — my children, or anyone watching my life — ask why I live the way I do, do I have an actual story of what God has done, ready to tell them, or only abstract explanations?
III. Obedience for Our Good, Always (vv. 24-25)
Moses ends with a striking summary: “The Lord commanded us to obey all these decrees and to fear the Lord our God, so that we might always prosper and be kept alive, as is the case today. And if we are careful to obey all this law before the Lord our God, as he has commanded us, that will be our righteousness.” Two things stand out. First, the purpose of obedience: “so that we might always prosper and be kept alive” — obedience for the sake of ongoing life and good, not arbitrary rule-keeping. Second, obedience itself is described as “our righteousness” — not a righteousness earned through perfect performance, but the appropriate, faithful response of a rescued people.
This closes the passage exactly where it began — with a God whose commands are for our good, and whose story is worth telling. Obedience isn’t a transaction to secure God’s favor; it’s the natural shape of a life already rescued and already loved.
Application Question: Do I view my obedience as an attempt to earn God’s favor, or as the natural, grateful response of someone who has already been rescued?
Conclusion
Israel was warned not to test God but instead to do what is right and good, trusting him rather than demanding proof. And when the next generation would eventually ask why, the answer was never meant to be an abstract argument — it was meant to be the actual story of rescue from slavery. May we, too, trust rather than test, and may we have a real story ready to tell whenever we’re asked why we live the way we do.
