It is Hard Not to Laugh!

Sunday 23 August 2026 Pastor Craig Ledbetter Genesis 18:1-15

I. Introduction (Genesis 18:1-15)

  • Do you really believe God’s promises? Or do you have your limits?
  • Remember He is God Almighty!
  • Let’s read Genesis 18:1-15

“And the LORD appeared unto him in the plains of Mamre: and he sat in the tent door in the heat of the day; 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” - Genesis 18:1,2

II. A Personal Encounter (Genesis 18:1,2)

A. Three Men Come to Abraham

  • Abraham is in the plains of Mamre - the most fertile area in all of Canaan
  • Three men are walking towards Abraham, and he jumps up and runs to greet them
  • Abraham doesn’t know who these men are - they look and sound just like normal guys

B. Who Are These Three Men?

  • Two of them are angels (revealed in Genesis 19:1)
  • The third is Jehovah God appearing as a man
  • “And the men turned their faces from thence, and went toward Sodom: but Abraham stood yet before the LORD” - Genesis 18:22

  • “And there came two angels to Sodom at even” - Genesis 19:1

  • If you ever meet an angel, you would never know it
  • “Be not forgetful to entertain strangers: for thereby some have entertained angels unawares” - Hebrews 13:2

  • Just be kind to people you don’t know - and especially to the people you do know!

III. Abraham’s Servant’s Attitude (Genesis 18:2-8)

A. Abraham’s Respectful Greeting

  • Abraham was super wealthy - 318 servants (Genesis 14:14), vast numbers of sheep, cows, and camels
  • Yet he was super plain living - living in a tent, content where God had placed him
  • And he was super respectful - he called the lead man “Lord” (Adonai - my superior) and bowed before them

B. Abraham’s Heart of Hospitality

  • “My Lord, if now I have found favour in thy sight, pass not away, I pray thee, from thy servant: Let a little water, I pray you, be fetched, and wash your feet, and rest yourselves under the tree” - Genesis 18:3,4

  • He offered to wash their feet - the most luxurious thing for dusty, weary travellers
  • He told Sarah to make bread quickly
  • He ran to the herd and fetched the best calf - tender and good - and cooked it himself
  • He stood by them as they ate, serving like a waiter (Genesis 18:8)
  • “Be kindly affectioned one to another with brotherly love; in honour preferring one another; Not slothful in business; fervent in spirit; serving the Lord… given to hospitality” - Romans 12:10-13

  • Abraham set the pace in his home - he commanded his household (Genesis 18:19)

IV. The Reason They Came (Genesis 18:9,10)

A. Two Reasons for Their Visit

  1. To announce the fulfilment of God’s promise - Sarah would have a son within a year
  2. To inform Abraham of the coming judgment on Sodom and Gomorrah (covered in later weeks)

B. The Promise Spoken Aloud

  • “And they said unto him, Where is Sarah thy wife? And he said, Behold, in the tent. 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” - Genesis 18:9,10

  • Notice he says “Sarah” - her new name - not “Sarai.” This stranger knew her name had been changed!
  • He speaks loud enough for Sarah to hear the promise herself

V. Sarah Needed to Believe the Promise Herself (Genesis 18:10)

A. Up Until Now, Sarah Had Only Heard from Abraham

  • Abraham had told her God promised them children - over and over
  • She trusted her husband enough to leave her home and family (Genesis 12)
  • But after years of waiting, she gave up and offered Hagar (Genesis 16)

B. Faith Must Be Personal

  • Faith comes not from your husband, not from your pastor, not from your denomination
  • “Faith cometh by hearing, and hearing by the word of God” - Romans 10:17

  • She needed to hear the promise from the mouth of the Lord herself
  • That’s why the prophets always said, “Thus saith the LORD” - not the church, not the religion

C. Four Things a Christian Must Trust

  1. The Promise of God - what He said He will do
  2. The Power of God - His ability to do anything
  3. The Presence of God - “I will never leave thee, nor forsake thee” (Hebrews 13:5)
  4. The Purpose of God - trusting that His will is good

VI. Sarah’s Laugh (Genesis 18:11-15)

A. The Reality of Their Situation

  • “Now Abraham and Sarah were old and well stricken in age; and it ceased to be with Sarah after the manner of women” - Genesis 18:11

  • Sarah was past the age of bearing children - there was no way physically
  • But Sarah’s reality means nothing to God’s ability!
  • No matter how impossible your situation is, God can do what He promises

B. Sarah Laughed Within Herself

  • “Therefore Sarah laughed within herself, saying, After I am waxed old shall I have pleasure, my lord being old also?” - Genesis 18:12

  • She was careful - she knew it would be rude to laugh at dinner guests
  • She was chuckling to herself, trying to hide it
  • She laughed in unbelief, just like Abraham had done (Genesis 17:17)
  • Her sin was unbelief - “Shall I of a surety bear a child, which am old?”

VII. The Problems With Unbelief

A. Unbelief Keeps People Away from God and Out of Heaven

  • What sin sends a person to hell? Unbelief
  • “But these are written, that ye might believe that Jesus is the Christ, the Son of God; and that believing ye might have life through his name” - John 20:31

  • “He that believeth on the Son hath everlasting life: and he that believeth not the Son shall not see life; but the wrath of God abideth on him” - John 3:36

  • Not believing in hell will not keep you from going there
  • The only requirement for entering God’s presence is faith and trust in Jesus Christ
  • “If thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved” - Romans 10:9

B. Unbelief Ruins the Christian’s Walk

  • Most Christians have no walk with God because they don’t believe much of what God says
  • When you mock God’s word and reject His promises, it hurts YOU
  • The reason Hagar was in Sarah’s home, and Ishmael became a thorn in their side, was because of unbelief
  • Too many Christians lose their joy of expectation of God’s promises

VIII. It’s Funny that Sarah Denies Laughing (Genesis 18:15)

A. Sarah’s Denial

  • “Then Sarah denied, saying, I laughed not; for she was afraid. And he said, Nay; but thou didst laugh” - Genesis 18:15

  • She doubted God’s word - just as Eve did when Satan said “Did God really say?” (Genesis 3:1)
  • Then she lied - she lied to God about laughing at God
  • Fear was controlling her actions - she was afraid of being exposed as an unbeliever

B. The Lord Exposes Her

  • “Nay; but thou didst laugh” - what a rebuke!
  • Very humbling, very brief
  • And then the conversation was over - the men rose up and looked towards Sodom (Genesis 18:16)

IX. God Is Qualified to Brag! (Genesis 18:14)

A. Is Anything Too Hard for the Lord?

  • “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” - Genesis 18:14

  • Only God can say, “Is anything too hard for me?”
  • Whatever He promises, He can do and He will do

B. Things God Cannot Do

  1. He cannot lie (Titus 1:2)
  2. He cannot die - that’s why He became a man as Jesus, so He could die for sinners
  3. He cannot deny anyone who believes in His Son
  4. He cannot save anyone against their will - your loved ones must choose to believe

C. What God Promises, He Is Able to Do

  • “Through faith also Sara herself received strength to conceive seed, and was delivered of a child when she was past age, because she judged him faithful who had promised” - Hebrews 11:11

  • “With God nothing shall be impossible” - Luke 1:37

  • After Sarah heard the words from the Lord and the rebuke, Sarah never doubts again
  • She judged Him faithful who had promised

X. Conclusion

  • Stop laughing at the impossibilities in your life - start believing God again
  • Be patient - Abraham and Sarah waited 25 years for the promise to be fulfilled
  • Stop trusting your own best efforts - even if they’re good, they may produce an Ishmael
  • Believe God beyond your imagination
  • “Now unto him that is able to do exceeding abundantly above all that we ask or think, according to the power that worketh in us” - Ephesians 3:20

  • “For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast” - Ephesians 2:8,9
