Why do so many think God is all-powerful, all-knowing, and all-loving?

[RFayette]

From a Biblical perspective, it's basically axiomatic that God is all-powerful and all-knowing - though it's important to note that in the triune godhead, the Word voluntarily took upon as part of humbling a relinquishing of total knowledge while on this Earth in Jesus's ministry, hence why he said he didn't know the time of his return (as part of the hypostatic union), however Jesus became omniscient when he was glorified after the Ascension.  With respect to God being all-loving, this is the toughest, but it's pretty clear.  God is love, but his vision of love is different than what we see.  Why?  Because God is perfect, and as such, he can't stand sin.  It's like a leaf and fire:  they're two different natures.  Sin repulses God so much, because he loves holiness....so yes, he is all love, but because he is love, he must hate sin.   So how can an all-loving God send people to hell?  Because sin is an utter affront to his holiness, and true love from a godly perspective demands holiness.
