Galatians 4:22

For it is written, that Abraham had two sons, the one by a bondmaid, the other by a freewoman.

The two sons set forth the position of the covenants, and that position is truth, belonging to a clear and convincing teaching that every candid, unprejudiced mind receives. The covenant position drawn from them is true light, and efforts to produce a different position waste investigative power.

Opposition to it repeats the manner of the Jews in interpreting and misconstruing the Scriptures, hanging on words and repeating and misinterpreting and twisting them to mean what unsanctified minds want them to mean, making false issues to cloud and mislead minds. Turning from this plain light comes from fear of having to accept what Galatians teaches about the law. No one is prepared to receive light either to establish or to refute a position on it until truly converted before God.
