"You will know a tree by its fruit." --Jesus
I am sure that we both would agree that if tomorrow 9 million Hindus became Budhists we would not marvel and think this was God at work. From the Budhist's perspective they might.
But we're not talking about non-Christian religions. We're talking about 9 million conversions to Christianity. Does that sound like the work of Satan?
"If Satan drives out Satan, he is divided against himself. How then can his kingdom stand?" --Jesus
So? Doesn't anyone stop and think that this person could have 1) been deceived or 2) been a deceiver?
Perhaps, except to say that God the Father is not recounted in the story. Mary is talking about coming to her, not the Father.
Sometimes Christians aid other people without invoking God's name. That does't make their actions intrinsically evil. Besides, in the account I read she identified herself as the Mother of God. She also instructed Juan Diego to go to see his bishop --to go to the Church. The connection with Christ's Church is quite clear.
1 Timothy 3:15And the magicians in Egypt were able to do miraculous signs. Simon in Acts was also.
if I am delayed, you will know how people ought to conduct themselves in God's household, which is the church of the living God, the pillar and foundation of the truth.
And the devil may appear as an angel of light.
But what fruit did these signs bear? Again, Satan would not work a sign that would result in the mass conversion of pagans. His kingdom would be divided against itself.
Jesus-"You will know a tree by its fruit."
If we want to use conversion as a measuring tool, we would have to say Islam is correct which is the fastest growing religion.
