I lived in an area of the U.S. that gets cold in the winter. Not cold according the definition of @shanijane+ (Shani Matthews) but cold. Really cold. It is not uncommon for it to get so cold that vehicles will not start. Your battery is dead. When that happens, you're not going to go anywhere unless you get a new battery or a "jump" from another vehicle that has a fully charged battery.
Nowadays things are a bit better than when I was girl. Now a lot of people have heaters to keep the battery from getting drained or they have a garage which keeps things from getting quite as cold. And they are making batteries which can withstand the cold much better as well. I remember the days though when there would be extended severe cold snaps and people would make sure they were starting their cars every couple of hours. If you didn't do this several times a night, you might not be going anywhere in the morning.
In this life we may be humming along nicely but then something happens. Our battery starts to discharge and may even go dead. When that happens, we need to get charged up once again by the Holy Spirit. He does that in a variety of ways; through the Word, prayer, a message we hear and even encouraging friends.
When you attempt to turn over your engine and nothing happens, don't despair. Remember that God is an expert and transforming dead batteries into living batteries. When we cry out to Him, He will get us back on the road again and who knows, perhaps you will find someone else who needs a jump.
