Old Testament Lesson:Genesis 17:15–21
15 And God said to Abraham, “As for Sarai your wife, you shall not call her name Sarai, but Sarah shall be her name. 16 I will bless her, and moreover, I will give you a son by her. I will bless her, and she shall become nations; kings of peoples shall come from her.” 17 Then Abraham fell on his face and laughed and said to himself, “Shall a child be born to a man who is a hundred years old? Shall Sarah, who is ninety years old, bear a child?” 18 And Abraham said to God, “Oh that Ishmael might live before you!” 19 God said, “No, but Sarah your wife shall bear you a son, and you shall call his name Isaac. I will establish my covenant with him as an everlasting covenant for his offspring after him. 20 As for Ishmael, I have heard you; behold, I have blessed him and will make him fruitful and multiply him greatly. He shall father twelve princes, and I will make him into a great nation. 21 But I will establish my covenant with Isaac, whom Sarah shall bear to you at this time next year.”
Epistle Lesson:Romans 9:6-13
6 But it is not as though the word of God has failed. For not all who are descended from Israel belong to Israel, 7 and not all are children of Abraham because they are his offspring, but “Through Isaac shall your offspring be named.” 8 This means that it is not the children of the flesh who are the children of God, but the children of the promise are counted as offspring. 9 For this is what the promise said: “About this time next year I will return, and Sarah shall have a son.” 10 And not only so, but also when Rebekah had conceived children by one man, our forefather Isaac, 11 though they were not yet born and had done nothing either good or bad—in order that God’s purpose of election might continue, not because of works but because of him who calls— 12 she was told, “The older will serve the younger.” 13 As it is written, “Jacob I loved, but Esau I hated.”
Gospel Lesson: Luke 13:22-30
22 He went on his way through towns and villages, teaching and journeying toward Jerusalem. 23 And someone said to him, “Lord, will those who are saved be few?” And he said to them, 24 “Strive to enter through the narrow door. For many, I tell you, will seek to enter and will not be able. 25 When once the master of the house has risen and shut the door, and you begin to stand outside and to knock at the door, saying, ‘Lord, open to us,’ then he will answer you, ‘I do not know where you come from.’ 26 Then you will begin to say, ‘We ate and drank in your presence, and you taught in our streets.’ 27 But he will say, ‘I tell you, I do not know where you come from. Depart from me, all you workers of evil!’ 28 In that place there will be weeping and gnashing of teeth, when you see Abraham and Isaac and Jacob and all the prophets in the kingdom of God but you yourselves cast out. 29 And people will come from east and west, and from north and south, and recline at table in the kingdom of God. 30 And behold, some are last who will be first, and some are first who will be last.”
Psalm 105: 1-11
1 Oh give thanks to the LORD; call upon his name;
make known his deeds among the peoples!
2 Sing to him, sing praises to him;
tell of all his wondrous works!
3 Glory in his holy name;
let the hearts of those who seek the LORD rejoice!
4 Seek the LORD and his strength;
seek his presence continually!
5 Remember the wondrous works that he has done,
his miracles, and the judgments he uttered,
6 O offspring of Abraham, his servant,
children of Jacob, his chosen ones!
7 He is the LORD our God;
his judgments are in all the earth.
8 He remembers his covenant forever,
the word that he commanded, for a thousand generations,
9 the covenant that he made with Abraham,
his sworn promise to Isaac,
10 which he confirmed to Jacob as a statute,
to Israel as an everlasting covenant,
11 saying, “To you I will give the land of Canaan
as your portion for an inheritance.”
Glory be to the Father, and to the Son, and to the Holy Spirit.
As it was in the beginning, is now and will be forever. Amen.
