I heard a good quote yesterday. It was from Kris Vallotton, one of the associate pastors at Bethel Church in Redding, CA. He said "We are fighting from victory, not for victory...but we are still fighting."
It's pretty awesome that Jesus has already won the battle over death for us and holds the Keys of Hell in his hands. As Christians we know the end of the story. We win! But, that doesn't mean we stop fighting against evil in this world. We can't sit idly by doing nothing till we die or are raptured. Also, we shouldn't panic like the world is going to end when the stock market crashes. It isn't the end of the world, and if it was we should have nothing to fear because we are victorious in the fact that Jesus has paid the debt of our sin on the cross!
