How can they prove THAT?

No two snowflakes are alike. Who said that? How can they prove it? Billions and ga-zillions of snowflakes have fallen since the beginning of time(one is too many for me),and no two are alike? C'mon, how can that ever be proven? I have to take it on faith that it is true.There are many things in my walk with The Lord that I have to take on faith. Forgiveness for one. To think that His death on the cross was payment for all of my sins,and when I screw up now, and ask for His forgiveness, and HE DOES FORGIVE ME,takes faith.I can't prove that my sins are forgiven, I can't prove that Jesus forgives me now when I ask,but by FAITH, I BELIEVE IT,I ACCEPT IT,in fact, I STAKE ETERNITY ON IT.
