Why does John divide people so sharply into those who love and those who hate? Are there not shades of grey in between? It is true that fallen human fathers still know how to give good gifts to their children (Luke 11:13), but only because God restrains them from becoming one hundred percent evil. It is also true that Christians may still be guilty of malice and other sins (1 Peter 2:1), but this is because the work of sanctification is not yet complete. Love and hatred are both trying to draw us entirely to themselves and possess us exclusively. If our behaviour is a mixture of the two, it is because the battle is not yet over. The unbeliever sides with sin, but the believer sides with the law of God.
