Every trip through the airport involves a walk by Auntie Anne's pretzels, where the aroma of sugar covered pretzels wafts across the concourse and always smells amazing. I don't know that I've ever actually had one, but the smell always brings joy.
Paul talks about Christ's death as a fragrant offering, and I think of it the same way. Christ dying on the cross is meant to waft around the community, bringing joy to those who were trapped in sin because they see the depth of God's love for them. It's strange that it would be death on a cross that would bring joy, but such is the love of God -- it will pay any price to redeem you from sin and despair. So the more we contemplate that, the more we are pushed to love one another, and so we then walk in love because of the great love with which Christ has loved us. The offering of Christ moves around the world, touching hearts, changing lives, and pointing us towards the kingdom of God.
