It is easy to 'move on' in life especially with so many significant causes globally but keep the poor, the hurting and the destitute in your view. This situation is somewhat unusual in it's intensity.
'Click cause' rage is of little help if it is simply a 'like' or profile pic change however keep in mind that solidarity and encouragement is found through such as well. It must be part of a broader action.
What is happening Iraq has been largely overlooked in light of the other (also deserving) issues facing the world at present. The Iraq situation is considered a 'hot potato' from a political perspective, governments are now making their moves but they are largely 'reserved' actions.
Social Network possibilities
Arabic 'N' – profile picture for facebook see link http://lifecitychurch.com/We%20are%20n.jpg
The Arabic letter 'N' – 'nun' has been used by ISIS to mark Christian households.
Use – the hashtag #WEAREN
A couple crucial points
a) Avoid generalisations – use ISIS or 'the Islamic State' not 'Muslims are...'
b) Remember that whilst Christians are very much central in this issue that other minorities such as Shia and Yazidi's also need our prayer and help.
c) Stay informed – feel the stories not just the statistics.
I would encourage you to also make it a public social request – post your question on their facebook wall and twitter. A public request encourages a public response.
France has already made the decision to specifically open it's doors to Christian refugees from this conflict. Encourage our government to do so as well (yes, I know in our present context 'Welcome' arms seem far from the norm in politics)
There are Christian organisations working on the ground to make a difference for those fleeing persecution. We are presently exploring some options that could be effective. For the moment we have included other reputable organisations that work in the ground.
