Dec 5 Trains ???how do they represent Advent???

Wednesday Dec 5 Trains...I have so many this year in my computer Christmas photo file..snow trains, Polar express, old fashioned and modern, in the wilderness and under the tree...how will I connect that to Jesus and Biblical Christmas? ... 1st is an all year thing...our youth pastor loves trains and uses them in his ministry...each time I hear or see a train or picture, I pause and pray for him and the youth he is influencing for the Lord. 2nd...they represent transportation and I am so thankful I do not have to travel long distances by foot or donkey [especially at term pregnancy as Mary did], by camel or horse as the wisemen did, but have choices of car, train, plane...The train is a dream transportation to me...dreams of more trips in the future and happy memories of trips in the past. I am blessed!!! God bless your Advent season in all forms of transport.
