Abraham is taught doctrine by the Lord and two angels appearing to him. The text demonstrates the Trinity through Abraham interacting with three beings (Gen 18:1-3). It also serves as a type or example for believers, as Sarah laughs at the promise of bearing a child in old age, just as Abraham did previously (Gen 18:12-13). Finally, the Lord affirms that nothing is impossible for Him and He will return as appointed to fulfill the promise of Sarah having a son according to the time of life (Gen 18:14).

1. Abraham is Taught Doctrine
Isa 28:9
Whom shall he teach knowledge? and whom
shall he make to understand doctrine? them that
are weaned from the milk, and drawn from the
breasts.
Text: Gen 18:1-14
Gen 18:1-14
1) And the LORD appeared unto him in the
plains of Mamre: and he sat in the tent door in
the heat of the day;

2. 2) And he lift up his eyes and looked, and, lo,
three men stood by him: and when he saw them,
he ran to meet them from the tent door, and
bowed himself toward the ground,
3) And said, My Lord, if now I have found
favour in thy sight, pass not away, I pray thee,
from thy servant:
4) Let a little water, I pray you, be fetched, and
wash your feet, and rest yourselves under the
tree:
5) And I will fetch a morsel of bread, and
comfort ye your hearts; after that ye shall pass
on: for therefore are ye come to your servant.
And they said, So do, as thou hast said.
6) And Abraham hastened into the tent unto
Sarah, and said, Make ready quickly three
measures of fine meal, knead it, and make cakes
upon the hearth.
7) And Abraham ran unto the herd, and fetcht a
calf tender and good, and gave it unto a young
man; and he hasted to dress it.

3. 8) And he took butter, and milk, and the calf
which he had dressed, and set it before them;
and he stood by them under the tree, and they
did eat.
9) And they said unto him, Where is Sarah thy
wife? And he said, Behold, in the tent.
10) And he said, I will certainly return unto thee
according to the time of life; and, lo, Sarah thy
wife shall have a son. And Sarah heard it in the
tent door, which was behind him.
11) Now Abraham and Sarah were old and well
stricken in age; and it ceased to be with Sarah
after the manner of women.
12) Therefore Sarah laughed within herself,
saying, After I am waxed old shall I have
pleasure, my lord being old also?
13) And the LORD said unto Abraham,
Wherefore did Sarah laugh, saying, Shall I of a
surety bear a child, which am old?
14) Is any thing too hard for the LORD? At the
time appointed I will return unto thee, according
to the time of life, and Sarah shall have a son.
