Pastor John MacArthur speaks at Grace Community Church's Shepherd's Conference in 2020. | Facebook/Shepherds' Conference Pastor John MacArthur has warned that culture is âsystematically designedâ and âweaponized to destroy childrenâ and stressed that God will severely judge parents who fail to raise their offspring âin the nurture and admonition of the Lord." "What we're facing today is fierce â I will confess â [but] of all the things that disturb me in this culture, of all the horrific, sinful, wretched, wicked, corrupt influences that go on in this culture, I think the thing that distresses me most is the war on children,â MacArthur, the pastor of Grace Community Church in Sun Valley, California, said in a sermon delivered over the weekend.
