Sometimes to get the most out of a gospel you have to make comparisons and contrasts within it.
For example, it is instructive to compare and contrast Nicodemus and the Samaritan Woman at the Well.
Nicodemus was a man. The Samaritan was a woman.
Nicodemus was well educated, the Samaritan woman was not.
Nicodemus was powerful among his people. The Samaritan woman was not.
Nicodemus was respected by his people. The Samaritan woman would not have been at the well when she was were she respected. She was likely despised.
Nicodemus was orthodox in his beliefs. The Samaritan woman's beliefs were deficient.
The two characters could hardly be more different. Yet both of them get the same message of salvation.
There is a lesson to be had there.
