No thanks for at least listing a few things you consider to be these mighty men,,,do you think we are just as guilty if we use the things they invented(computers,cars ect.) when we know that they are doing these things(slavery,pollution ect) and do you think we would be deserving of the same punishment?
As it Is written, there is no good or evil in any thing,
and,
it is the human heart which produces wickedness.
A computer can be used to save lives, share the gospel, or to promote lies, or to facilitate abuse.
If we have a renewed heart we have to personally weigh up our actions on the scales of God's wisdom and with the measure of His love.
He makes all things beautiful in His time, if we can do everything for the glory of God, we may yet be able to use what others intended for evil, to work the good deeds of God on this earth.
We have to be careful and not judge before the time.
Martha was cross and wanted Mary to help serve with her, Jesus defended Mary, saying she had chosen a better thing than serving Him.
A woman who "wastefully" poured costly perfume on Jesus' feet, instead of selling it and donating to the poor, was publicly defended and commended for her incredible act of love by the saviour.
But we do know that the love of money is the root of all evil, and therein we see once again, it is the wicked unhealthy desire, and not the money itself that is evil. These modern day mighty men we speak of, tend to accumulate great wealth and this is (I speak generally) frequently a higher priority to them than moral decision making.
This is why it is harder for a rich man to enter the kingdom, than for a camel to pass through the eye of a needle. It is rare for a Godly person to willingly accumulate wealth , when there are so many needs in the word, all the time.
But, ultimately, only God knows why we choose to sell, buy, own, or use things, and only He can properly judge our justification for doing so. If the things have only the purpose of aiding someone to sin, or strongly support sinning in some way, we can be clear it is not to be bought, sold or used by a believer.
