Galatians 2:19

For I. In the Greek the pronoun “I” is emphatic. Whereas in v. 18 Paul speaks as if he were one of the Judaizers, he now refers to personal experience (vs. 19-21).

Through the law. By personal experience in seeking salvation through compliance with the requirements of the legal system Paul had proved to his own satisfaction the inefficacy of that system. Furthermore, he now saw that the law pointed the sinner to Christ.

Dead to the law. That is, have nothing more to do with it. Formerly Paul had expected to be justified by careful compliance with all the law’s requirements. This had been the objective of his life. Now that the law’s true purpose had become clear to him he realized that he could expect no help from that source. Accordingly, he had abandoned the legal system altogether as a means of salvation.

Live unto God. His life was now oriented toward God, as it had formerly been toward the law. His purpose in life was now to appropriate the means of salvation God had graciously provided (see Phil. 3:13).
