Okay, Christmas bells aren't ringing and there's no snow to merrily glide across. However, imagine that you are living back in the midwest, it's winter and the sky is dark and dreary. No clouds are single, but all married to each other, forming one big family of gray. Blizzards are howling and clawing at your door, for three long days, until finally they're over and have left you a visual reminder of their presence with drifts of white, glistening snow, six feet deep. And, you've got to walk a mile to town... just like Laura Ingalls...
Sometimes, our problems and circumstances are so long and deep that walking through them is just like pushing through that soft, deep snow. Trudging, one step at a time. Will frostbite set in? Will your legs hold out? Will you ever reach your destination, where a warm fire awaits to relieve and revive you?
God has given us a safe assurance that the answer to all of the above is a resounding 'yes'! Isa 43:2 "When you pass through the waters, I will be with you; And through the rivers, they will not overflow you. When you walk through the fire, you will not be scorched, Nor will the flame burn you. For I am the LORD your God, the Holy One of Israel, your Savior..."
And that's why we can go merrily, merrily through the snow - no matter how packed it is!
