Guys, I will be having prayer group this week and I've asked my backslided Christian friend to join me this week and said okay but he said he's backslided and doesn't really believe in God anymore. I'm here to seek some help from you guys as to what to say to him to convince him that our God is the true and living God who cares and loves Him in the hope that he would return to His embrace. Scriptures might or might not work in this instance but I hoping for some answers that non-Christians or backslided Christians could easily and readily grasp.

Thank you all
