Peter Kreeft

God's interventions are miracles: events that cannot happen by merely natural agents but only by a supernatural agent. They no more interfere with our free will than natural events like earthquakes. We choose how to respond to them.

Anyone, without exception, can know God if they really want to simply by praying, by honestly telling Him that they want to know Him. He always responds to honest seekers. Jesus promised, 'All who seek, find.'
