And the Lord appeared to him by the oaks of Mamre, as he sat at the door of his tent in the heat of the day. He lifted up his eyes and looked, and behold, three men were standing in front of him. When he saw them, he ran from the tent door to meet them and bowed himself to the earth and said, “O Lord, if I have found favor in your sight, do not pass by your servant. Let a little water be brought, and wash your feet, and rest yourselves under the tree, while I bring a morsel of bread, that you may refresh yourselves, and after that you may pass on—since you have come to your servant.” So they said, “Do as you have said.” And Abraham went quickly into the tent to Sarah and said, “Quick! Three seahs of fine flour! Knead it, and make cakes.” And Abraham ran to the herd and took a calf, tender and good, and gave it to a young man, who prepared it quickly. Then he took curds and milk and the calf that he had prepared, and set it before them. And he stood by them under the tree while they ate. They said to him, “Where is Sarah your wife?” And he said, “She is in the tent.” The Lord said, “I will surely return to you about this time next year, and Sarah your wife shall have a son.” And Sarah was listening at the tent door behind him. Now Abraham and Sarah were old, advanced in years. The way of women had ceased to be with Sarah. So Sarah laughed to herself, saying, “After I am worn out, and my lord is old, shall I have pleasure?” The Lord said to Abraham, “Why did Sarah laugh and say, ‘Shall I indeed bear a child, now that I am old?’ Is anything too hard for the Lord? At the appointed time I will return to you, about this time next year, and Sarah shall have a son.”” (Genesis 18:1–14, ESV)Grace and peace to you from our Lord and Savior, Jesus Christ. Amen.
Sarah was skeptical. And who could blame her. She was 89 years old. “The way of woman had ceased to be with her”. So, technically, it was impossible for her to have children. She laughed at having a son. God would call the child “He laughs”, Isaac, pointing to her doubt. “Is anything too hard for the Lord?” God indeed does what is impossible, notwithstanding Sarah’s doubts.
When you consider the context of the text, you can see how all this was set up. Abraham looks up and “suddenly” three men were standing before him. Abraham knew it was a special appearing of God. All at once they were there. His reaction says so. Abraham bowed down to the ground in worship. He offers them what he has. His actions were urgent; quickly ran to the tent to ask Sarah to prepare bread. He ran to the herd to get a calf to slaughter.
The contrast is quite strong. Mary and Martha like. Martha was busy with much service. Martha is busy in the tent. Mary was sitting a Jesus’ feet. Abraham is clinging to faith while he listens to the Lord. What Abraham saw, was God’s appearing, God’s presence with them. Did Martha just see three visitors?
In a way, you can’t blame her. God appeared in a plain ordinary way. Three travelers. There was no lightning, no thunder, no kings, no temple. Only a tree, a tent, a meal and a kitchen. But God was there, and he was there to offer Sarah a promise.
Where is Sarah your wife? She is in the tent.God continues:
“I will surely return to you about this time next year, and Sarah your wife shall have a son.”Sarah was skeptical. She laughs at the promise. Maybe it was all too simple. Maybe unlike her husband, she didn’t see God in the three visitors. But she laughs at the thought of having a son. God is faithful, just like he was to Martha.
Mary has chosen the good portion, which will not be taken away from her. Luke 10:42:
Is anything too hard for the Lord?And God was faithful, even when Sarah doubted. He came with a word of promise, and Sarah hears it. She has a son of promise. Maybe she doubted from the outset of the promise 25 years earlier, or maybe her hope just faded. But until the baby was born, who could blame her.
So, here we sit, week after week, month after month, year after year. We come to hear God’s promises. We come to receive his forgiveness—won by Christ. It is delivered faithfully by God, even when we are faithless. We wait in weakness. We wait with doubts. There are distractions and even laughter at the idea that God could use our weak, little congregation to do anything. That he can bring life from bareness and joy from sorrow.
We sit here in our temporary space; the same space used for LGBT+ celebrations and speak our quiet words of God’s hope and promise. While our building project struggles at every step; red tape, shifting timelines, and unexpected delays. It’s enough to make us laugh like Sarah. It’s enough for us to ask the question Did God really want us to build?
We sit in doubt when our prayers go unanswered. Like Sarah, who must have thought that God had long forgotten about his promise of children like the stars of the sky. Family issues persist with no end in sight. A child that has gone astray. A brother or sister that refuses to be reconciled to us. Healing from a deep emotional wound. Prayers about our community, our country and the world seem to go unanswered. Natural disasters pile up, our prayer seems ineffective. Maybe he doesn’t hear my prayers. The doors seem closed. Has God forgotten about me?
But God is faithful. Not because we have a great vision. Not because we have made a great plan. Not because we are persistent in prayer, or not. Not because we are strong. But because he is faithful above all our doubts and all our sorrows and all our frustrations. The same Lord Jesus who comes to us faithfully every Sunday is the same Lord who sat beneath the oaks of Mamre. He comes to us in Word and Sacrament. He comes to us in preaching. He comes to us when, as he promised, we gather where two or three are gathered in his name. The same Lord who said, ‘I will return, and Sarah shall have a son,’ now says to us: ‘I am building My Church. I am with you always. Take and eat… given for you.’
Now, I want to speak very clearly here. Our church project doesn’t have a clear promise from God. In fact, after all that we do, it could still fail. Our church could fail. But even in the face of all that, God is still faithful. His promises are not tied our plans, our buildings or our budgets. God doesn’t promise we will always see the fruit of our prayers. The promises he makes to us are tied to Christ. He is not going anywhere. Even if we worship in a tent, even if we lose every earthly support, we still have everything—because we still have Him. Our hope is not in brick or wood, but in the cross and empty tomb. And that promise stands, even if everything else falls.
So, while the foundation still isn’t poured, we don’t look to our success. While we are frustrated with waiting on God to answer our prayers, we look to the cross. We come here because this is where we hear of God promises anew. The cross is where God’s promises are given and received in full. We look to what God does in his church, children are baptized, Christ’s body and blood are given, the Word is proclaimed in faithfulness. This is where we pray continually for the church, the world, our nation, and all people. And this is where we see it. This is why we gather, small as we are, week after week, month after month year after year. God’s promise is true. Is anything too hard for the Lord?
There are doubts. We are more like Sarah than we want to admit. But with those doubts we cling to the cross. Jesus tears down sin and death by sacrificing himself for us. He hung there—not in glory, but in weakness and shame and blood. He bears the curse of our failures. He bears our doubts. He bears our pride. He bears our sorrows. He bears our frustrations. He bears our fear. The cross is stronger than any human sin. The cross is stronger than any human frustration. The cross looks like failure, but it is where God is most at work. There he is as work for you and me. That is where we find our hope, no matter what happens. No matter how dark our lives get. No matter how frustrations cling to everything we do. Christ is still crucified for us. Christ is still risen for us. Christ is still here for us. Christ is still coming again to end all frustration, sin, fear, doubt and failure. And because of his promises, proven at the cross, it means we are still his beloved church. Amen.
The peace of God that passes all understanding, keep your hearts and minds in Christ Jesus. Amen.
