During the Old Testament, only the High Priest could enter into the Most Holy, behind the curtain (Heb.9:7). When Jesus died, this curtain tore "from top to bottom" (Mat.27:51) giving us direct access to heaven.
Our bodies are "temples of the Holy Spirit" (1Cor.6:19). The question is: Did we die with Christ? (Gal.2:20) Did the curtain in our hearts tear from top to bottom, to allow the Holy Spirit into our Most Holy, there where we hide our biggest and darkest secrets?
Remember, ONLY the Gospel can tear the curtain separating our heart from the heart of God, shake us out of our world of sin and prevent our life-boat from sinking!
