Hello everyone:
Well there are a lot of things that can be applied to this matter. One of them is that we are under grace and our lord Jesus Christ is a God of Love and HE is waiting patiently so that all can repent and come to the knowledge of knowing Him.And if it was like in the old testament believe me a lot of believers would get judged also. Mormons,JW,Cults and all kind of this Satan's lies are wrong we Christians all know that, but lets not forget that we sin daily I am not talking about continual sin but daily stupid sins which we all should repent of. But I think if God was not a gracious God he would of probably destroyed most of Christians also because a lot of them to things which are not contrary to our lord. So I think as Christians we should not think as to why is God not destroying this people but we should pray so that God would give them a chance to repent and see the light. Sooner or later those people who don't repent are going to die and go to hell but I think it is our job as Christian's to be a living testimony to them and witness o them so that they will convert. There are daily thousands of people whose eyes are open from the lies of Satan and they turn to Christianity if God had destroyed them believe me our great great grandparents were probably one of them, if God had destroyed them well I got news for you guys we wouldn't of been here. We all should ask God so that he through the Holy Spirit should give us compassion for this people instead of thinking why are they alive. We should pray and go witness to them the truth. Well brothers and sisters we should also remember that our God is a God of love and in due time he will Judge all the unrighteous.
Lord Bless.
