Karl Marx insisted that “religion is the opium of the people,” while Napoleon Bonaparte suggested that “religion is what keeps the poor from murdering the rich.” But within the broad category of religious belief are ideologies and practices that are dangerous and silly because they distract people from the essence of truth. God made it simple by having His Son do for us what we could never do on our own—reach God! Religion takes what is simple and merely complicates it.

This teaching is from the series Always Only Jesus with Skip Heitzig from Calvary Church.
