"So then, brothers, stand firm and hold to the teachings we passed on to you, whether by word of mouth or by letter." - 2 Thessalonians 2:15
My wife and I collect lighthouses. We visit them while on vacation and regularly add to our collection of miniatures and pictures. Lighthouses remind us of being a light in the darkness and a guide to the wayward. They are those great stone edifices that stand firm in the storms and send forth the light that saves from a watery grave. God also places lighthouses on the shores of this world to save souls from eternal damnation.
Paul writes of coming days of increasing evil and tribulation. He assures believers of their deliverance from this time, but until those days arrive he calls us to stand firm and hold to the teachings passed down to us. The winds of time may bring change, but the truth remains the same: Those who refuse to love the truth will perish, and those believe the truth will live eternally. As we spread the light of this truth, we are God's lighthouses.
