Well, OK, it kind of is. But more importantly it’s also about the resurrection!
The Cross is a beautiful place, where Jesus became sin for us so that we could live and have freedom to worship God. I love the Cross and I go there often because I need constant reminding about where my strength comes from.
The resurrection is better though. Without the resurrection the Cross would be an empty gesture, without any power to save. The fact that Christ rose again is absolutely essential, and the resurrection is what we celebrate at easter. On good friday Jesus’ died, and on easter sunday he rose again.
We celebrate Sunday, as the completion of what began on Friday.
