Siwon tweeted half an hour ago along with the picture above saying:

God hates sin, but God loves the sinner. Everyone has a mistakes, No worries! He loves us always

In the picture, group member donghae can be spotted too! I guess donghae and siwon is in the same praying group? Netizens commented on his tweet saying,
'What a lovely thought! I was all upset about something I watched on the news this morning, but what you said just calmed my soul! Thank you!' and 'Honestly oppa, i totally love ur quote sooo true thx 4 da great lesson '.

It seems like Celebrities can be a great but good influence to people too!
They are not always like what's reported on the news, instead they can be of
good influence to people!
