Just as we want to give all of our time/attention/money/etc. to that special person in our life or the hobbies we love, we should feel even more the same way about God. In Mark 14, verse 3, a woman (probably Mary Magdalene) poured a jar of expensive oil on Jesus' head. This perfume was made with pure nard and was worth a year's wages. Imagine using a full year's wages in a quick moment to honor someone you love. For many, that is unfathomable.
