Allah subḥānahu wa ta'āla (glorified and exalted be He), can make the impossible possible
Take a look at a part of surat Maryam about prohpet Zakariya (as):
A mention of the mercy of your Lord to His servant Zakariya.
When he called upon his Lord in a low voice,
He said: “My Lord! surely my bones are weakened and my head flares with hoariness, and, my Lord! I have never been unsuccessful in my prayer to Thee:
And indeed, I fear the successors after me, and my wife has been barren, so give me from Yourself an heir,
who will inherit me and inherit from the family of Jacob. And make him, my Lord, pleasing [to You].”
So his prayer was answered and he was told that there’s good news:
(Allah said) “O Zakariya ! Verily, We give you the glad tidings of a son, His name will be Yahya (John). We have given that name to none before (him).”
Now, imagine being told by Allah swt that there's good news. Surely, if Allah swt says it’s good news, than it must be very good news.
So, Zakariya was very old when he made this du'a and his wife was barren so you could say it’s impossible for him to get child. However, he did not hestitate to call upon His Lord, because he has faith and knows that Allah swt is the best of all planners. What an inspiration, subhan'Allah.
So, whenever you want something, but it seems impossible remember this,
Zakariya (as) was surprised ofcourse, so he said
“Lord! However can I have a youth and my wife is barren, and I have already reached the decrepitude of old age?”
And Allah swt reply was, Subhan'Allah absolutely beautiful:
He said: So shall it be, your Lord says: It is easy to Me, and indeed I created you before, when you were nothing.
So, please, brothers and sisters, never lose hope. Allah swt is The Almighty. We say this every day, yet how many times do we stop to realise that if we really want something (and work hard for it) and pray for it, we can get it because to us it seems like something big. But to Allah swt? To Allah it isn’t big at all.
Don’t think that Zakariya (as) got this only because he is a prophet. No, he had so much faith and hope in Allah swt, that Allah swt made his wish come true. I think Allah swt, wants us to know this by using this example.
He also used in this surah the example of Maryam (as) having Jesus (as).
