Then Abraham fell upon his face, and laughed, and said in his heart, Shall a child be born unto him that is an hundred years old? and shall Sarah, that is ninety years old, bear?
Therefore Sarah laughed within herself, saying, After I am waxed old shall I have pleasure, my lord being old also?
And Sarah said, God has made me to laugh so that all that hear will laugh with me. And she said, Who would have said unto Abraham, that Sarah should have given children suck? for I have born him a son in his old age. And the child grew, and was weaned: and Abraham made a great feast the same day that Isaac was weaned. And Sarah saw the son of Hagar the Egyptian, which she had born unto Abraham, mocking. Wherefore she said unto Abraham, Cast out this bondwoman and her son: for the son of this bondwoman shall not be heir with my son, even with Isaac. And the thing was very grievous in Abraham's sight because of his son. And God said unto Abraham, Let it not be grievous in your sight because of the lad, and because of your bondwoman; in all that Sarah has said unto you, hearken unto her voice; for in Isaac shall your seed be called. And also of the son of the bondwoman will I make a nation, because he is your seed.
And as for Ishmael, I have heard you: Behold, I have blessed him, and will make him fruitful, and will multiply him exceedingly; twelve princes shall he beget, and I will make him a great nation.
And God heard the voice of the lad; and the angel of God called to Hagar out of heaven, and said unto her, What ail you, Hagar? fear not; for God have heard the voice of the lad where he is.
Thus saith the Lord, In an acceptable time have I heard you, and in a day of salvation have I helped you: and I will preserve you, and give you for a covenant of the people, to establish the earth, to cause to inherit the desolate heritages;
(For he saith, I have heard you in a time accepted, and in the day of salvation have I succored you: behold, now is the accepted time; behold, now is the day of salvation.)
And God said, Sarah your wife shall bear you a son indeed; and you shall call his name Isaac: and I will establish my covenant with him for an everlasting covenant, and with his seed after him.
And he said, I will certainly return unto you according to the time of life; and, lo, Sarah your wife shall have a son.
He that sits in the heavens shall laugh: the Lord shall have them in derision.
The Lord shall laugh at him: for he sees that his day is coming.
But you, O Lord, shall laugh at them; you shall have all the heathen in derision.
Draw nigh to God, and he will draw nigh to you. Cleanse your hands, you sinners; and purify your hearts, you double-minded. Be afflicted, and mourn, and weep: let your laughter be turned to mourning and your joy to heaviness. Humble yourselves in the sight of the Lord, and he shall lift you up.
Sorrow is better than laughter: for by the sadness of the countenance the heart is made better.
Then was our mouth filled with laughter, and our tongue with singing: then said they among the heathen, The Lord has done great things for them.

Abraham and Sarah laughed, but was it righteous laughter? Ishmael who mocked the weaning of Isaac was it a cause for laughter? After we humble ourselves, we will experience the laughter of the Lord and we will sing and proclaim the greatness of the Lord's judgment because the Lord is not playing. And the Lord worked it out for Abraham's which is for our good because we love God and we are the called according to his purpose. Ishmael was the beginning of the salvation package and Isaac was the end of the salvation package, which is sorrow being turned to joy and the joy is everlasting.
Everything is so funny nowadays, you see so much on youtube and television that makes you laugh, but is your laughter righteous? Is it any profit?
