We can see an illustration of what Jesus’ death accomplished for us when we put both our hands out in front of us. They are both lit by the light above. But if a large black book is placed above one hand, this hand is now in darkness. This represents our sin. Jesus is represented by the ’sinless’ other hand, which is still in fellowship with the light. Jesus, as our substitute, takes our sin (the big black book) upon himself and so we can be reconciled to God. See 2 Corinthians 5:21.
