–20 as Paul continues his argument that the Mosaic Law was temporary — a guardian preparing God’s people for Christ. With Christ’s coming, believers move from slavery under the Law to sonship through the Spirit. Paul warns the Galatians that returning to observing the Law’s calendar and regulations is a regression into bondage promoted by the Judaizers. He appeals personally, reminding them of their former love for him and expressing pastoral anguish until they fully grasp the sufficiency and completeness of salvation in Christ alone.
