Granny23, there are many, many atheists who do good work but also have other interests, what difference for a Christian? I think you are seeing everything in practical acts and disregarding that time spent in payer gives many the strength and courage to carry out the most exhausting and for some most dangerous practical acts. I have dear friends in a silent order , they do not leave the convent, have little sleep, when I write I have no idea which sister will reply because forming personal friendships is not permitted. These women give up so much to spend their lives in prayer, I think their work is exhausting, demanding and for the good of mankind so I cannot agree they would do more if they lived a different life, to answer such a calling takes great courage and a deep love for mankind .
Time spent in prayer is a necessity for a Christian , I do what I can to help people but several times a year I enter a retreat house, I need this time of solitude , it's healing. So I think you judge harshly sorry
