Different things catch my eye and when I saw this sign, I did a double take. As I walked by, I mused about the local Catholic church, using a map grid, dividing up the neighbourhood and parishioners faithfully walking and praying for protection for their block. I was impressed.
Then on a subsequent walk, I read the sign more closely. According to Wikipedia, Cathodic protection is “a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell.”
Corrosion?…I thought a bit and kept reading….”a simple method of protection connects the metal to be protected to a more easily corroded “sacrificial metal” to act as the anode. The sacrificial metal then corrodes instead of the protected metal.”
Hmm…are we like the metal being connected to and protected by Jesus our “sacrificial metal‘? He offered himself, was ‘corroded’ and died on the cross for our screw ups, instead of us.
I continued reading and learned that cathodic protection is not adequate for long structures like pipelines and “an external DC electrical power source is used to provide sufficient current”. Sounds to me like the Holy Spirit that Jesus said he would leave to comfort us. Did you know too, that cathodic protection can “prevent stress corrosion cracking.” Thank You Lord for your constant love and protection. We do not need to crack or corrode under stress, we just need to trust You.
