While Europeans carried away African gold, Ivory and resources, missionaries told Africans to wait on the lord and that their reward was in heaven. The Europeans preachers stood on African soil, holding bibles printed with African resources, preaching to Africans that earthly wealth was vanity . While preaching, the African wealth was quietly taken away. Today ,the same wealth they told Africans as vanity upon vanity is what sustaining the Europeans.
A true believer of the Christian fellowship would not reason this way as you do and I hope this discussion does not call for criticism because I am aware that there bad been this religious war that condemns other religions while those especially that practices the preaching of the Gospel by the teaching of the Bibles are victims of this religions criticism.
However, those so called resources you claimed the Europeans stole/took from the African lands is a misconception rather, it was idols (image) which our ancestors worshipped in reference to their maker (God Almighty) that is said to be taken away from the lands in other to teach us (Africans) the true gospel in regards that we have only one true God which was demonstrated true the existence of Jesus Christ's miraculous performance and his resurrection.
There came the 10 commandments included the passage that said thou shall not worship other God except thee which our ancestor worshiping of the images was against the law.
I grew up to meet my grandpa and as an African, he advised us his children not to worship idols which are the images you said the Europeans took because, it has it side of evil practices.
I am not trying to troll as I also understand that we have our different ways of religious beliefs while some are Atheist.
So, that you tend to describe is not resource as long as others sees the images as their idols.
