In our study of Hebrews chapter two, we look at the fact that Jesus was human as well as the Son of God. This chapter reminds us that God came down as a man because that was the only way that we could be saved. In chapter one, we saw that Jesus was higher than the angels but here we see that He humbled himself and became lower than the angels for our salvation.
"We must pay more careful attention, therefore, to what we have heard, so that we do not drift away." NIV translation
Anytime we see the word "therefore", we must look back to what we have studied before because what is to come is connected to that. Here, we are reminded that Jesus is God as He was higher than the angels. The "drift away" speaks to the fact that many will accept the fact that Jesus was a great man (which is true) but they will forget (deny) that He is the Son of God. It seems that we see that even more today as people call themselves Christians (disciples of Jesus Christ) yet deny the words that He said about Himself (Son of God). They, in fact, have drifted away from the Gospel of Jesus Christ.
"For if the message spoken by angels was binding, and every violation and disobedience received its just punishment, how shall we escape if we ignore such a great salvation? This salvation, which was first announced by the Lord, was confirmed to us by those who heard him." NIV translation
In the Old Testament, God used angels to deliver His instructions and disobedience (sin) resulted in punishment. Then, God sent His Son to save us because we could not live up to His standards. If breaking the law resulted in punishment, will not rejecting the salvation that is offered through His Son result in even worse judgment. Not only do we have what Jesus said about Himself but we also have the eyewitness accounts of those who walked the earth with Him and learned directly from Him.
"God also testified to it by signs, wonders and various miracles, and gifts of the Holy Spirit distributed according to his will." NIV translation
Here, we see that the truth of the gospel of Jesus Christ was not only established by the words of the witnesses but by actions as well. Many times, we ask about the purpose of the miracles that we read about in the Bible and here we are given the answer as they all point to the fact that salvation through Jesus Christ is God's plan for us.
