They are built to stand the test of time.
But their survival is no mere accident. Each part of the tree – from top to bottom – was built to survive and thrive, even through the greatest threat to a tree - fire. Even their seeds point to this truth.

Iron sharpens iron, and one man
sharpens another ~ Proverbs 27:17

Sequoia trees are survivors.

A sequoia seed can only be accessed through fire. Only intense heat will open the cone after the fire has passed to allow the release of the seed to then be planted. Only the presence of pain allows for planting and growth to take place. Sequoias become massive mature trees only through the pain of testing by fire.
