God speaks to those coming to worship him (v.2). He lays out how they can reenter covenant with him (v.3-8) . He illustrates the irrationality of letting them continue how they are and not having any terms of the covenant (8-11). He states that he will use destruction and punishment because they do not follow him. V.19 shows it is ultimately to their own shame. V.28 shows discipline is meant to be accepted by the people to turn them back to God. V.12-15 reinforces this idea, as God cites the destruction of another place to try to motivate his people to turn to him. He reminds them of the covenant he made with their fathers and how it involved both religious practices (sacrifices, burnt offerings, etc.) and spiritual devotion (following God in all ways) (v.22-23). What was the demise of these people? Simply that they did not listen or pay attention to God (v.24-26). This is a violation of the spiritual side of the covenant. They then (Or maybe before? Or at the same time? We don’t really know I guess but it doesn’t really matter, we need both.) violated the religious side (v.17-19, v.21, v.30-31).
The idea that these people are beyond the help of prayer (v.16) is also illustrated in Ch.8. They are totally rejecting grace so that it is no longer possible to offer it to them (7:27-29).
The crime of not listening to or paying attention to God is frightening to me. I can easily forget or ignore just about anything and there are several things I don’t pay attention to. This can be a good thing at times, but also very dangerous. I must make God a priority and completely immerse myself in him if I want to remember, learn and pay him the attention of which he is so greatly worthy.
