Surely it is written in the Law that Abraham had two sons, one by the slave-woman and one by the free-woman;

but since we know a man is justified simply by faith in Jesus Christ and not by doing what the Law commands, we ourselves have believed in Christ Jesus so as to get justified by faith in Christ and not by doing what the Law commands ??for by doing what the Law commands no person shall be justified.

Then the Law is contrary to God's Promises? Never! Had there been any law which had the power of producing life, righteousness would really have been due to law,
