The Yoke
The 'yoke' refers to the burden of the Mosaic Law, which some were attempting to impose on Gentile believers.
This symbol highlights the transition from the Old Covenant, based on the Law, to the New Covenant of grace through faith in Jesus Christ. It underscores the freedom believers have in Christ, free from the legalistic requirements of the Law.
In ancient times, a yoke was a wooden beam used between a pair of oxen to enable them to pull together on a load. It symbolizes burden and servitude.
