Exercise involving a written confession of sin: Write you sin/s on paper. Then fold the paper in half to symbolise a ‘closed’ chapter. Take the paper to a large wooden cross where there is a hammer and nails. Nail your confession to the cross and leave it there. (Audible impact of the sound of the hammer hitting the nail and visual impact of the sight of a confession plastered cross.)
