Hebrews 6

http://www.esvbible.org/Hebrews+6/

The author of Hebrews says that he shouldn't have to keep going over the elementary things because, while they are an important foundation to start with, there is so much more that we should learn in order to fulfill our highest potential in Christ. Some people once found salvation, and they even experienced God and what the powers of His love can do; however, they ended up deserting Christ. By disgracing Him publicly, the author of hebrews compares it with crucifying Christ a second time. He also says that they cannot be led back to Christ. Once they've been there, and they turn away for some reason, they are lost forever. You cannot convince them to make right with God. God blesses the Earth and often lets rain fall on it. This rain produces useful crops; however, if it produces thorns and thistles, they are worthless and will be burned. If God pours into you, and you use that to praise Him, worship Him, and pour into others, you are useful to Him. On the other hand, it He pours into you, and you turn away from Him with a hard heart, nothing can help you. You will eventually end up in Hell.

Even though the author of Hebrews seems to be convicting his audience, he says he only does so because he knows that God has great things in store for these people. They have done great things, and God will remember that. God will remember the things you do for Him and reward you based on your intentions. We should all work hard to prove that we are confident in what we have placed our faith in. Then, we won't be lazy but will follow the example of those who receive the promises with faith and patience. When God first made an oath to Abraham, He had no one on whom to make the oath, so He made it on Himself. People make oaths on people higher than themselves to set up credibility. If they don't fulfill the oath, the oath breaker has to respond to the higher authority. There is no one greater than God, so He can only make oaths on Himself. God cannot break His oaths, and He has proved this because He never has. God made His oaths to encourage us, that we have the chance of one day living in His presence. Those of us who believe hold onto these constants as anchors for our lives.
