Several time in the Word the Lord tells us that there is nothing that is impossible for him.
There is nothing “too hard” for the Lord.
We find this truth in the Abraham story.
Sarah had heard the news.
They would have a son next year.
She laughed…to herself…while at the door of the tent…hidden behind the door?
And the LORD said unto Abraham, Wherefore did Sarah laugh, saying, Shall I of a surety bear a child, which am old?
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.
The Lord told Abraham that Sarah had laughed at the Word.
The Lord tells Abraham via question - is any thing too hard for the Lord?
The unstated answer is “no”.
The Lord then tells him He will return at the appointed time.
According to the time of life, gestation - nine months later.
Sarah would have a son.
The Lord had repeatedly spoken and confirmed His Word.
The Son of the Promise was coming.
The Promise had been given more than 25 years before.
Trust in the Lord.
He is faithful and what He has promised, He will do.
