Galatians 5
Freedom of the Believer
1 For freedom Christ has set us free. Stand firm, then, and do not be subject again to the yoke of slavery.
The Greek word for "be subject again" is ἐνέχω (enechow), a present middle imperative verb, meaning a command to not become ensnared in a yoke of slavery.
The yoke was the wooden harness that was placed around oxen who were plowing a field. Paul informed the Galatians that at one time, they were ensnared by a wooden harness who were plowing a heavy field. The load was too heavy for them. However, Christ came and set them free. He warned the Galatians to stand firm in the faith. The firmness comes from the study of the Word of God. If they would stay firm in the Word of God, then they would not be ensnared to the same slavery of their former condition. The slavery is the Mosaic Law. It is impossible to keep. It is a heavy burden that cannot be carried. The Galatians did not need to go back under this yoke, since Christ had set them free.
Carnal Christians do not appreciate freedom and education. They do not understand God's sovereignty. They do not understand their role in this life. They live for self instead of for Christ.
