We are reminded about worship and service through the story of Mary pouring out an obscenely expensive bottle of nard (perfume) onto Jesus' feet. This is worship because Mary gave this perfume, equal to one year's wages, to Jesus. This was everything that she had. It was service because she cleaned Jesus feet with it and her hair. She was demonstrating for all to see what sacrifice for Jesus looks like!
When the church worships and serves in this way, people notice. There was a literal fragrance left by Mary. However, there was also a metaphorical fragrance as well. When we worship and serve Christ, people notice. You leave this fragrance of Christ behind!
