In the Book of Hebrews, the author gives the Jewish believers of the time a lesson on faith. He does so by providing several testimonies of Old Testament people who demonstrated faith in the way that pleases God. Since it is impossible to please God without faith, then those who seek to please God would be smart to examine the faith of those people mentioned, and copy their responses to life's circumstances. The Book of Hebrews defines faith as the substance of things hoped for and the evidence of things unseen. Since faith is both "substance" and "evidence" then faith is observable. Faith is not something that is claimed, but rather is something that is done.
One of the examples of faith in Hebrews chapter 11 is of Noah's testimony. The New Testament explains that as one studies the testimony of Noah, one can see the type of faith that God is interested in. Thus, the lesson provided in Genesis 7:1-10 is helpful for those who seek to please God through faith. In Genesis 7:1-10 the Bible explains that God spoke to Noah after Noah completed building the ark. Therefore, the first lesson in faith that is taught is that those who possess faith seek the voice of God and are obedient to His Word, trusting it to be true. Though Noah did not have experience building large barges, and likely wasn't qualified to manage and care for the lives of thousands of animals, Noah did the things that God instructed him to do, trusting in God's ability to perform rather than his own ability (or lack thereof).
Genesis 7:1-10 states that as God spoke to Noah after he built the ark, God confirmed the righteousness of Noah. Since Noah demonstrated faith through obedience to God's Word, God considered him righteous. The Bible is specific to state that Noah alone was righteous. In this way, the Bible suggests that Noah was the only one paying attention to the voice of God and responding in obedience to demonstrate faith. Therefore, the Bible teaches that faith is not behavior that is reflective of the majority. Faith is not a manner of conduct that most people participate in. The Bible explains that faith is reflective of conduct that is contrary to the ways of the world. Consider the statement of God: Noah alone was righteous. This means that Noah placed himself on an island of sorts, separating himself by his faith. Since his trust in God's Word was so rich, his behavior and conduct was seemingly opposite everyone else in the world, which would have made it very difficult for Noah to relate to others. Nevertheless, this reality did not keep Noah from trusting in God. Noah sought to please God rather than people, and God considered him righteous as a result.
Genesis 7:1-10 states that God desired to have specific inventory on the ark concerning the animals. The scriptures show that God wanted seven pairs of "clean animals" and two pairs of "unclean animals." The scriptures state that, though God would destroy every living thing on the earth, He had a plan to continue with life on the earth so that He stocked the ark with enough animals to repopulate the earth after the flood. As God gave His specific instructions, the Bible reveals that Noah did everything that the Lord had commanded him. In this way, the scriptures show that Noah's faith was not short-lived, but it endured and reflected a sense of urgency. God had warned Noah that He would judge the earth in 7 days. Thus, Noah had just one week to prepare his family, himself, and preform the necessary tasks associated with organizing the animals that God would bring to the ark. The Bible shows that Noah did everything that God had commanded showing that Noah continued to believe in the judgment of God and as a result, demonstrated urgency in his obedience.
Consequently, the Lord showed favor to Noah, confirming the scriptures to be true. God is pleased with faith. Noah showed faith. His faith was observable. The proof of God's coming wrath was evident in Noah's conduct. The substance of hope that Noah possessed in God's promise to save him and his family was demonstrated by the urgency Noah showed towards God's commands. As a result, God was merciful to Noah, but also gracious towards his family. Although the Bible is plain to show that Noah alone was righteous, Noah's family received the benefits of His righteousness. God worked this way purposefully to show that the righteousness of one can be imparted unto others. In this way, the faith of Noah allows God to use his example as an illustration of Christ. In the same way that righteousness is imparted unto those who have faith in Jesus Christ, righteousness was imparted unto the family of Noah. In the same way that the righteousness of Christ saves those with faith from the judgment and wrath of God, so too was Noah's family saved from the judgment and wrath of God because of Noah's righteousness.
Since salvation from the eternal judgment of the Living God only comes by faith in Jesus Christ, God provided pictures in the Old Testament to show what saving faith looks like and what it accomplishes. Though Jesus was not yet born, John 1:1 states that Jesus first existed as the Word of God so that as Noah trusted in God's Word, it was equal to Him trusting in Jesus Himself. Thus, Noah is no different than any believer today. The emphasis and focal point of saving faith has always been on the Jesus Christ as the Word of God. Since God does not change, it is no surprise that Noah and his family was saved then as people are saved today. Finally, the Bible proves that Noah's faith was not in vain. God promised that He would flood the earth in seven days after Noah completed the ark. Genesis 7:1-10 confirms that as Noah obeyed the Lord and did all he was commanded to do, seven days later the flood came upon the whole earth proving Noah's faith to be the only thing that facilitated his opportunity to live.
