Does God use unbelievers?
I mean bless them?

According to the bible,the blessings of abraham passed onto the gentiles.
And The gentiles are connected into that blessing through the sacrificial work of Jesus Christ.
Before Jesus' death, only the Jews,covenant people could enjoy that blessing. NOw,it's open to all.
But, when an influential person in the world/or society is an acclaimed Christian, preachers are quick to attribute his success to his being a christian.
Isaac Newton is used as an example of a man greatly blessed by God in the area of intellect because he was a __ .
(fill in the blanks)
But what of those, who arent, or are avowed atheists, etc?
It poses a threatening question to those who think otherwise.
People who say that outstanding success is only achievable by Divine favour. Meaning, Newton and his type,
pleased God hence God showered them with smarts.
These examples are broken.
ONe can point at many people all over the world who are luminaries and yet dont give a damn about God!
Others backslided and most became lukewarm if there were ever hot after their success. Others were just nominal. Their christianity was just in name.

The bible says, All good gifts come from above!
So all knowledge that has benefitted the world and made it better ,most of it,if not all came from God!
Break throughts in medicine that made polio and malaria a thing of the past came from __ ? Certainly not the Devil?

It's impractical for all major ideas to come from only one religious group!
The is an estimate of about 1b christians on the planet.
of that 1b, a much smaller percentage would have the intellectual acumen to qualify to advance a field. Centering all output from them would render the other 6b redundant. I know,man is selfish and tribal and cliquey but God is wise.

The bible also says that God causes rain to fall on the roof of the just as well as the wicked! the unsaved and blasphemers enjoy some of God's blessings!
When God had in mind for man to conquer the air thru flight, He was going to channel his idea through a person with an engineering mindset!
Not otherwise.
The internet,the radio,the telescope,
the computer,the automobile,cellphones,mattresses, vaccines,x-ray,etc Great ideas from the mind of God-good things- but realized thru many times, unsaved minds!!
