6 And Sarah said, God hath made me to laugh, so that all that hear will laugh with me.
7 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.
Genesis 21 v 6-7
This verse is Sarah’s reaction after giving birth to the promised child Isaac. Now the thing about this verse is, Sarah is asking “who would have believed? Surely it is an incredible thing that someone as old as I am, as old as my husband Abraham could actually bare a child!”
Yet what Sarah is actually doing is reflecting on her past disbelief, and her past doubt, because we saw in Genesis 18 v 13-14 that she had actually laughed when God suggested that she would have a child at her old age:
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.
15 Then Sarah denied, saying, I laughed not; for she was afraid. And he said, Nay; but thou didst laugh.
Genesis 18 v 10 – 15
And sometimes we have to do that.
Don’t take for granted the times that you have trusted God after periods of doubting Him – acknowledge it. Acknowledge it in the place of prayer, acknowledge it in your private study time with God, in fact, testify about it.
What Sarah was doing was shaming herself in order to bring glory to God. She was saying “you know what, I doubted God, but God is faithful.” In that moment of celebration, she acknowledged that there had been tribulation, and that she had been weak in her faith. She did not have the faith that her husband had, and yet God still came through.
13 If we believe not, yet he abideth faithful: he cannot deny himself.
2 Timothy 2 v 13
And that is the glorious thing about God. The bible tells us that He is faithful even when we are faithless because He cannot deny Himself, so it doesn’t matter if you have ever laughed at the idea of God doing it for you in the past, trust that He CAN.
And when God does come through for you, celebrate, testify, make sure that you let someone else know of God’s goodness. Make sure that you really give God the thanksgiving that He is deserving of.
