Along with some fun games, and a time of worship, there was a short talk.
The speaker, James, used a section from Acts - Ch 28 v3-6:
3 Paul gathered a pile of brushwood and, as he put it on the fire, a viper, driven out by the heat, fastened itself on his hand. 4 When the islanders saw the snake hanging from his hand, they said to each other, ‘This man must be a murderer; for though he escaped from the sea, the goddess Justice has not allowed him to live.’ 5 But Paul shook the snake off into the fire and suffered no ill effects. 6 The people expected him to swell up or suddenly fall dead; but after waiting a long time and seeing nothing unusual happen to him, they changed their minds and said he was a god.
James made the point that we need to "shake off our snakes", or words to that effect - the things that are holding onto us that keep us far from God.
We all have things like that, we need to ask God to help us shake them off into the fire, where they can't hurt us, or hold us back any more.
I realise that it was a youth service, and I've not been a youth for many years, but I found it helpful.
