Wow, @luchyl, this is huge... A total stranger? God works in a mysterious way, his ways are unfathomable.
Most times we pick such unknown phone calls, we will quickly drop it telling the caller, "wrong number" but not knowing the purpose behind it, thank God you had time chatting with him.
Yeah, God can use anyone to bless someone. His ways are truly unknown.
Whenever I pick such calls from unkwon number, I always try to be nice because I don't know who might be calling.
Yes, anyone can be an angel sent to help us, thank you.
