Browsing pictures of St. Patrick's Cathedral the other day, I found this aerial view. Notice that the cathedral has been designed in the shape of the cross, with the sign of the cross mediating between heaven and earth.If we are to be spared the punishment of God, the cross of Jesus Christ must stand between us and him. That's at the heart of the gospel. The cross is our shield, in the sense that our faith in Jesus' death for our sins protects us from the eternal consequences of unbelief and disobedience.
The cross is more than protection, however. Faith in Jesus Christ brings not only forgiveness but a restored relationship with God, access to God. We can bring our cares, worries, doubts, and fears to him knowing that he cares for us as our children. The cross is not only a shield, but a bridge.
I love you, O Lord, my strength!
The Lord is my rock and my fortress and my deliverer,
my God, my rock, in whom I take refuge,
my shield and the horn of my salvation, my stronghold.
I call upon the Lord, who is worthy to be praised,
and I am saved from my enemies.
- Psalm 18:1-3
