Any voice that pulls us away from the work of Jesus is a voice that needs to be shut up by the voice of God. The voices that leave us with no sense of worth, love, or acceptance need to be silenced with death and resurrection. From spiritual commitments to family relationships, job performance, and self-image, Satan will speak his lies to make us believe that we're not good enough.
The scandal of the cross is that on the cross Jesus becomes the worst of sinners. On the cross the record of sins gets handed to Jesus and it gets buried in the tomb with Jesus. On the cross an execution event becomes a transaction in the divine economy. God pays with his life and we receive what only he could afford.
Our world can hardly fathom the idea of a pure gift. Gifts seem to only be for the deserving. They're a transaction for those who've earned our appreciation or our attention. But, thanks God, Jesus is God's indescribable gift for us.
Karma suggests that everybody gets what they deserve. This worldview is appealing to the world but if it is true, everyone is screwed.
