By faith Noah, when warned about things not yet seen, in holy fear built an ark to save his family. By his faith he condemned the world and became heir of the righteousness that comes by faith.
Some speculate that before the flood, the earth had never seen rain. There are alot of theories that go along with this, and many of them make sense, but imagine Noah being told that the earth is going to be destroyed by water. Very hard to believe, yet he believed it, and staked his entire reputation on it.
He preached for years, condemning the world, without a single convert. He followed God's instructions. He lived in a way that convinced his family, and his family, in full submission to him, followed him and his faith.
He became the recipient, not only of a salvation from the waters, but of a salvation from the evil world that surrounded him. He was an heir to righteousness because of this faith.
Thousands of years before Paul wrote about salvation, men were being saved by grace through faith.
Are we willing to follow God's commands today? Are we willing to stake our reputations on this Jesus? Are we willing to stand out, like a boat in a desert, for Christ?
Choose to follow after God today in holy fear.
