I posted this several years ago. It still resounds with me.
And [Jesus] could do no miracle there except that He laid His hands on a few sick people and healed them. And he wondered at their unbelief (Mark 6:5-6).
Of all places, Nazareth should have been the town where people flocked around Jesus. After all, it was the place He'd grown up -- the place His mother and family still lived. Yet, the Lord couldn't perform miracles there because His former neighbors thought they knew Him too well. Jesus is simply a carpenter, the son of Mary who lives down the street.
Like Jesus' neighbors and childhood friends, perhaps a reason we rarely see God's power in our lives is because the Jesus we grew up with is too familiar. Many of us have known about Him ever since we were in the cradle. We know the stories and the things He taught. We know about His mother and father. We know about His friends and disciples.
So our knowledge of Jesus lulls us into familiarity. Familiarity dulls us into complacency. And complacency hardens us against His ability to miraculously live out His life within us.
Perhaps that is why Jesus said, The kingdom of heaven is like a merchant seeking fine pearls, and upon finding one pearl of great value, he went and sold all that he had and bought it (Matthew 13:45-46).
The familiarity-complacency cycle can only be broken when we decide to seek the Pearl as if He is unreservedly the most important thing in our life.
