Those from His hometown thought they knew Him. They saw Him grow up after all. A carpenter. A nice young man, but nothing special really. So when He blew their minds by what He did and the words He spoke, they took offense. Because He didn’t behave in the way they had come to expect.
Our own filters can blind us to who Jesus is and what He is doing, though perhaps in a different way. We explain away His words that don’t match up with what we believe (or our own experiences) instead of letting them reveal more of who He is. We get upset and offended because He doesn’t heal, doesn’t provide, doesn’t work in the way we think He should. And so we take offense, pushing Him away.
We can’t figure God out, but we can get to know Him. More. Each day. If we let Him break our filters.
