Contemporary English Version (CEV)
The lesson here is that there was a place where we could not go. Our sin separated us from the holiest part of the temple, and there was no path in. A high priest entered the space once a year, but for the rest of us, we were doomed to sit outside and lament our sin, hoping against hope that mercy might trickle through to us.
Instead, God brought the curtain separating us crashing down, and mercy radiated out to transform us through the sacrifice of Jesus Christ, who willingly crossed the barrier so that we might be brought into the full presence of God through his atonement for our sin. Only through Christ do we find the path to true life, and so we go boldly forward in his holy name.
