These devotions are part of the Follow the Word Bible reading program at St. John Lutheran Church in Cypress, Texas. This year we are reading through the Scriptures together, listening for how God speaks through his Word day by day. I hope you will join me on this journey.
Today’s readings are Numbers 13-15, Psalm 70.
Numbers 14:11-19
And the Lord said to Moses, “How long will this people despise me? And how long will they not believe in me, in spite of all the signs that I have done among them? 12 I will strike them with the pestilence and disinherit them, and I will make of you a nation greater and mightier than they.”
13 But Moses said to the Lord, “Then the Egyptians will hear of it, for you brought up this people in your might from among them, 14 and they will tell the inhabitants of this land. They have heard that you, O Lord, are in the midst of this people. For you, O Lord, are seen face to face, and your cloud stands over them and you go before them, in a pillar of cloud by day and in a pillar of fire by night. 15 Now if you kill this people as one man, then the nations who have heard your fame will say, 16 ‘It is because the Lord was not able to bring this people into the land that he swore to give to them that he has killed them in the wilderness.’ 17 And now, please let the power of the Lord be great as you have promised, saying, 18 ‘The Lord is slow to anger and abounding in steadfast love, forgiving iniquity and transgression, but he will by no means clear the guilty, visiting the iniquity of the fathers on the children, to the third and the fourth generation.’ 19 Please pardon the iniquity of this people, according to the greatness of your steadfast love, just as you have forgiven this people, from Egypt until now.”

In the midst of Israel’s wanderings toward the Promised Land, an important lesson on prayer emerges. The spies are sent to scout out the land and return with two dramatically different reports. The majority report can be summarized simply: “Don’t go there! The people there will squash us like ants! We’ll be killed the first step we take into the land.” Joshua and Caleb, however, bring a report springing from courageous faith: “Let us go up at once and occupy it, for we are well able to overcome it” (Numbers 13:30).
Then (predictably) comes the grumbling of the people. You’ve brought us out here to die. We don’t need to go into this dangerous place. We’re going to die in the desert.
Then comes God’s anger at their faithlessness.
“And the Lord said to Moses, ‘How long will this people despise me? And how long will they not believe in me, in spite of all the signs that I have done among them? I will strike them with the pestilence and disinherit them, and I will make of you a nation greater and mightier than they.’”
Moses has been formed by the challenges and victories he has experienced, and he is stronger for it. He has spoken with God on Mount Sinai. He has endured the criticisms and disappointments. He has seen the Red Sea parted and the manna from heaven.
Bolstered by these experiences, Moses stands in the gap before the Lord on behalf of the people, serving as a priest for them – a glimpse of the greater mediator who would one day stand in the gap for all.
In doing so, he makes his boldest appeal:
“Now if you kill this people as one man, then the nations who have heard your fame will say, ‘It is because the Lord was not able to bring this people into the land that he swore to give to them that he has killed them in the wilderness.’ And now, please let the power of the Lord be great as you have promised.”
See what Moses is doing? He is calling God on his promise. He is taking God at his word.
Centuries later a man by the name of Martin Luther prayed for his friend and colleague Philip Melanchthon. According to accounts preserved by friends and later biographers, Luther found Melanchthon nearly unconscious. Luther took hold of him and began to pray very forcefully and directly to God.
In his own way, Luther was doing what Moses had done.
Luther later described what he did something like this (paraphrased from various early reports):
“I prayed for Philip with great urgency, because the need was extreme. I pleaded God’s promises and reminded him that he had commanded us to pray. I besieged God with his own promises. I threw the sack at the door.”
It was Luther’s vivid way of saying that he laid the whole matter before God and pressed God’s promises in prayer.
There are times when you can do the same. You can throw the sack at the door of God’s grace and pray the strongest prayers of all – prayers grounded in God’s Word and promises.
Prayer is not powerful because of the one who prays. It is powerful because of the God who hears – the God who has given his promises and invites us to hold him to them in prayer.
