Big Idea:  God’s People Never Leave God Standing on the Front Porch of their Lives.

I  The LORD Appeared to Abraham 1-2

1 Now the LORD appeared to him by the oaks of Mamre, while he was sitting at the tent door in the heat of the day. 2 When he lifted up his eyes and looked, behold, three men were standing opposite him; and when he saw them, he ran from the tent door to meet them and bowed himself to the earth,

II  Abraham Invited the LORD to stay 3-8

3 and said, “My lord, if now I have found favor in your sight, please do not pass your servant by. 4 “Please let a little water be brought and wash your feet, and rest yourselves under the tree; 5 and I will bring a piece of bread, that you may refresh yourselves; after that you may go on, since you have visited your servant.” And they said, “So do, as you have said.” 6 So Abraham hurried into the tent to Sarah, and said, “Quickly, prepare three measures of fine flour, knead it and make bread cakes.” 7 Abraham also ran to the herd, and took a tender and choice calf and gave it to the servant, and he hurried to prepare it. 8 He took curds and milk and the calf which he had prepared, and placed it before them; and he was standing by them under the tree as they ate.

III.  The LORD spoke to Abraham and Sarah 9-15

A.  The Lord promised that in one year, Sarah would have a son 9-10a

9 Then they said to him, “Where is Sarah your wife?” And he said, “There, in the tent.” 10 He said, “I will surely return to you at this time next year; and behold, Sarah your wife will have a son.”

B.  Being past the age of childbearing, Sarah laughed at this promise. 10b-12

And Sarah was listening at the tent door, which was behind him. 11 Now Abraham and Sarah were old, advanced in age; Sarah was past childbearing. 12 Sarah laughed to herself, saying, “After I have become old, shall I have pleasure, my lord being old also?”

C.  The Lord confronted Sarah for laughing, and repeated His promise. 13-15

13 And the LORD said to Abraham, “Why did Sarah laugh, saying, ‘Shall I indeed bear a child, when I am so old?’ 14 “Is anything too difficult for the LORD? At the appointed time I will return to you, at this time next year, and Sarah will have a son.” 15 Sarah denied it however, saying, “I did not laugh”; for she was afraid. And He said, “No, but you did laugh.”

Application:  How Do God’s People Welcome God into their Lives?

1.  INVITE: We must invite Him into our lives. While we are forever saved from sin simply by trusting in God for eternal life–we are challenged daily to invite Him to be the Lord over every part of our lives.

2.  SERVE: We must see ourselves as servants of God.

John 13 12 So when He had washed their feet, and taken His garments and reclined at the table again, He said to them, “Do you know what I have done to you?  13 “You call Me Teacher and Lord; and you are right, for so I am.  14 “If I then, the Lord and the Teacher, washed your feet, you also ought to wash one another’s feet.

3.  TRUST: We must choose to trust God’s promises to us, even when we are tempted to doubt Him.

Rom 4:19 Without becoming weak in his faith, Abraham accepted the fact that he was past the time when he could have children. At that time he was about 100 years old. He also realized that Sarah was too old to have children. 20 But he kept believing in God’s promise. He became strong in his faith. He gave glory to God.  21 He was absolutely sure that God had the power to do what he had promised.
