All your good deeds (anyone’s good deeds) in the world and the biggest amount of love and kindness you have (or anyone has) won’t keep them out of the lake of fire and away from the eternal torment that is in store for everyone...
It’s only the Gospel by way of Jesus, the Messiah of Israel and one’s trust and faith and acknowledgment of His saving sacrifice on your behalf that will do that.
It’s a mistake to get people to think that by “doing good” and by “showing love” that they are being better and therefore, giving them the false impression that they are “good people” and deserve to go to Heaven. If they do all the good in the world — they only deserve to go straight to hell... on just that basis...
I’m not arguing theology of salvation with John MacArthur, but Christians are supposed to be salt and light. They are supposed to change the world, and they have done so in the past. How is he contributing to that? I ask again: Is there absolutely nothing good in the Roman Catholic and Orthodox Churches? Is there no reason at all to join with them against forces which are downright Satanic? Is there no difference to him between the RCC church and the “church of Marx”?
I am a little confused.
You seem to be saying that “the lake of fire” and Jesus are specifically connected. So far as I can determine “lake of fire” is taken from Revelations which was written well after Jesus’ death.
