Mary's act of anointing Jesus' feet with expensive perfume reveals what true devotion looks like. She didn't calculate the cost of the year's wages worth of nard but poured it out in worship, filling the house with fragrance. While Judas criticized her waste, Jesus defended her sacrifice. Real devotion to Christ requires positioning ourselves at His feet, carrying His fragrance through the fruit of the Spirit, and being willing to sacrifice financially and socially. True love for Christ always involves personal sacrifice because that's the nature of love itself.
