Again He said, "Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least (or, of no account) in the kingdom of heaven." Matthew 5:19.
The Apostle James said, "For whosoever shall keep the whole law, and yet offend in one point, he is guilty of all." James 2:10. Keeping nine of the commandments will not save us. If we break one commandment, the law will condemn us as surely as if we broke all the ten.
Man can not change one single commandment of God's law. If he tries to do so, it is then only a commandment of men. The worship of those who make or keep such commandments is useless, for God will not accept it. Christ said of those who do so, "But in vain do they worship Me, teaching for doctrines the commandments of men." Matthew 15:9.
The only safe course is to take God's law just as He gave it on Sinai, and obey it as He gave it. Of those who will be alive when Christ comes it is written, "Here are they that keep the commandments of God." Revelation 14:12.
Heaven will be filled with commandment-keeping people; for it is written, "Blessed are they that do His commandments, that they may have right to the tree of life, and may enter in through the gates into the city." Revelation 22:14.
We can not keep these commandments ourselves any more than the children of Israel could in the wilderness. It is for this that Christ died on Calvary. Through Him we can have forgiveness for our sins, and receive help to overcome sin and obey the law of God.
While Moses was in the mount God gave him instructions for building the sanctuary. It was to be like the one in heaven. In it the Lord would meet His people and give them such instruction as they needed. Provision was also made in it for sacrifices and offerings, all of which were to show their faith in the Saviour to come.
Moses was in the mountain one-ninth of a year. The faith of the people was not strong enough to endure the long separation from their leader. They did not think he would return to them. They said, "As for this Moses, . . . we wot not what has become of him."
They came to Aaron and said to him, "Up, make us gods, which shall go before us." They would make to themselves a calf as their leader to take the place of Moses, and then go on to the promised land without him. The old habits of idol worship in Egypt had come back to them.
