In Hebrews 10:29, the Lord calls upon us to think about the blood (life) of Christ in such a way that we are NOT to consider what He did for us as something common or ordinary. I am afraid, however, that many people who identify themselves as Christians do exactly that. They come and they go just as they please, never really considering that their actions directly reflect against them in the Lord’s eyes. Lives lived liked this reflect a disposition as if it does not really matter. But, it does matter. It matters to the Lord and, in time, it will matter to the one who so lives. A life lived in this sort of way, intentionally or not, is a life lived that tramples underfoot the Son of God (cf. Heb. 10:29). It is a shame that the person who lives this way actually thinks he (she) can and will stand prepared to meet the Lord! They are delusional in other areas also. RT
The occasion surrounding the Lord’s judgment on Nadab and Abihu is one of serious importance. From it we learn that God’s servants much approach Him in holiness. It has been common for the Jewish rabbis to interpret the sin of the brothers to be directly connected to alcohol, but the Lord does not say this. What we do learn from the Lord is that which they offered was profane, or unauthorized (Leviticus 10:1). Gordon Wenham wrote in regards to this situation, “…the closer a man is to God, the more attention he must pay to holiness and the glory of God” (Leviticus, p. 156). It’s a serious matter, and to him who is given much, much is expected.
