Such a contrast between Numbers and the ritual sacrifices and cleanness that formed a key part of the Law of Moses, and Galatians, where “the righteous shall live by faith”. We’re so blessed to have been offered life through Christ, rather than condemnation under the law, to have an inheritance based on God’s promise.
Solomon writes “whoever despises the word brings destruction on himself, but he who reveres the commandment will be rewarded”. Knowledge of God is important to appreciate all that He has done for us, and to understand that “we are not children of the slave but of the free woman”, just as the Galatians needed to understand the true gospel.
