Some things in life are just impossible. For example, it is impossible for a virgin to give birth to a child (well, except with current medical interventions). It is impossible for a dead person to come back to life (John 11:44). It is not normal to be subtracting from something and yet for that thing to be increasing (Proverbs 11:24)

So when Mary said to the angel; ‘how can this be’? She wasn’t being unreal.

“Then the angel said to her, “Do not be afraid, Mary, for you have found favor with God. And behold, you will conceive in your womb and bring forth a Son, and shall call His name Jesus . Then Mary said to the angel, “How can this be, since I do not know a man?”
Luke 1:30‭-‬31‭, ‬34 NKJV

That is why I can understand how you feel about taking that seemingly impossible step. It is practically impossible to achieve success as is.

Well, my Bible tells me ‘nothing is impossible with God’, and that includes every possibly impossible thing.

The question then is; ‘are you doing it on your own or with God?‘

“Commit your way to the Lord , trust also in Him, And He shall bring it to pass.“
Psalms 37:5 NKJV

God is the One who brings impossible things to pass.
