A Blessed Household

Is Christ's death a general atonement? What does it mean to be blessed? What does it mean to teach children in the Way that they should go? Is John talking about his own physical children? Why did they go to Jerusalem to worship? Why did God have to forebear? Why is agreement in Christ vital for fellowship? Why can't those who are blessed tolerate a false gospel? Does God need anything from anyone to save? What division does Christ cause among people?
