In some ways it is easy to have a holiday club. You can just run it the same way as last year.
Just rope in some leaders from the youth organisations, arrange a few games, sing 'Jesus' love is very wonderful' and hit them with a few 'old-faithful' Bible stories.
Or . . . you could have a successful holiday club!! Yes, if you want your holiday club to achieve anything this year, it will take prayer (didn't I mention that?) vision, fresh thinking, hard work, committed leadership, planning, preparation, and, of course, more prayer.
