Holy Saturday is for me a day to pause by the darkness of the resurrection that has not happened. On this day after the crucifixion, the initial shock would have worn off enough for the disciples to recognize that they have awoken to a world where everything they believed has shifted. It is a fitting day to remember and empathize with those whose faith is shifting and/or for whom the hope and joy of Easter feels absent.
To help you do that, Kathy Escobar does a wonderful job of writing about helping those whose faith is shifting: http://kathyescobar.com/2015/03/09/friends-of-faith-shifters-things-that-help-things-that-hurt/
