”..one of the reasons Christ went to the cross was to make the way for us to know and understand truth.”
Jesus came to bear witness to the truth. All those who love the truth will come into the light, those whom God has mercy on.
Those who hate the truth will stay in darkness, for they hate the Truth, they hate Christ.
Yet, Jesus says, “Come unto Me all.” Many will not come, becuase they hate Him. And they will cast out into darkness, the Jew first, and also the Gentile.
If you go and tell all sinners that everyone will be in heaven one day, even if you don’t repent and believe the gospel: the death and ressurection of Christ, then you my friend are in dire straits.
paul said anyone who preaches a different gospel will be accursed. In fact, he includes himself, if he would ever preach a different gospel he says let himself be accursed.
