In the walk from the city centre to the hill of Crucifixion, understandably Jesus would have been close to death and unable to go on for much longer as the cross he was carrying would have been far to heavy.
It is at some point in the journey he falls and the solders start to beat him to make him carry on, but he had seemed to lose all strength to lift that cross anymore.
Standing in the crowd was a Cyrenian guy called Simon. I'm not sure what happened but I imagine Simon may have tried to get the solders to show a bit of respect to Jesus, or maybe even tried to help Jesus as he struggled on the ground.
What ever happened Simon was told by the solder to carry the cross for Jesus. This to me has a important part to play in the story and in the bible.
At the point in the journey as Jesus hit a point that he just couldn't carry on alone Simon was the one to take up the challenge with him. Jesus had been almost beaten to his death but Simon was fresh and had the strength to help Jesus.
Jesus would have realise that this was the only way he was going to get to the end and needed Simon's help to see him through.
We all have times when we just cant do it alone. We need people around us. We need support from others. Even as Christians it is essential to have the support of the Church.
Jesus experience our struggle to receive him. He experienced the what it was like to not be able to carry his burden alone. he experienced the feeling of having to depend on others to keep him alive.
He know, and he know the inability we have to carry our burdens alone.
