How does the Law relate to evangelism, conversion and believers? My understanding of these issues from the book of Galatians are found below:
1. In regard to evangelism, the Mosaic law can be used to prick a person’s conscience (i.e. using the Ten commandments). But it does not save people and it was historically for the people of Israel.
2. In regard to conversion, the Mosaic Law cannot save anyone. It was to contain sin until Christ came to fulfill the promises made to Abraham, namely, to bless the world.
3. In regard to the believer, we are not under the Mosaic Law. This does not mean, however, we are lawless because we obey the commandments of Christ.
