Num 15:32-36 While the people of Israel were in the wilderness, they found a man gathering sticks on the Sabbath day. And those who found him gathering sticks brought him to Moses and Aaron and to all the congregation. They put him in custody, because it had not been made clear what should be done to him. And the LORD said to Moses, “The man shall be put to death; all the congregation shall stone him with stones outside the camp.” And all the congregation brought him outside the camp and stoned him to death with stones, as the LORD commanded Moses.
For the deed was done with unblushing boldness in broad daylight, in open defiance of the divine authority—in flagrant inconsistency with His religious connection with Israel, as the covenant-people of God. (Brown)
Those are to be reckoned presumptuous sinners, who sin designedly against God’s will and glory. Sins thus committed are exceedingly sinful. He that thus breaks the commandment reproaches the Lord. He also despises the word of the Lord. Presumptuous sinners despise it, thinking themselves too great, too good, and too wise, to be ruled by it. A particular instance of presumption in the sin of sabbath-breaking is related. This was done as an affront both to the law and to the Lawgiver. God is jealous for the honour of his sabbaths, and will not hold him guiltless who profanes them, whatever men may do. God intended this punishment for a warning to all, to make conscience of keeping holy the sabbath. And we may be assured that no command was ever given for the punishment of sin, which, at the judgment day, shall not prove to have come from perfect love and justice. The right of God to a day of devotion to himself, will be disputed and denied only by such as listen to the pride and unbelief of their hearts, rather than to the teaching of the Spirit of truth and life. (Henry)
I wonder how many times we just go about our days and give no thought to how some of our thoughts, words, or actions may be sinning against God. Neglect of God’s Word will certainly lead to giving no thought to the things of God, and in this state of living, there is little hope of knowing that which pleases God or is pleasing to God, yet alone, that which honors and glorifies Jesus Christ.
