"Were you there when they crucified my lord"

This song is a really old song, but I was thinking about easter and all the songs we do in my church and what songs could we do this year and this line came into my head, so I sat with it for a while and then began to look at the deeper meaning.

Obviously none of us were actually there at the time when Jesus was nailed to the cross, but I can't help but think in some way that parts of us were. Not my actual being - but my sins are what put him on that cross, he died for my faults, my human weakness. Its in our sins that were there.
I really love knowing that Jesus died for me, but its not a morbid thought - its the thought that I have been set free, he gave his life so I can live mine.
