The children of your Father which is in heaven. Matthew 5:45.
The best name by which we can think of God is Father. It is a loving, deep, sweet, heart-touching name, for the name of father is in its nature full of inborn sweetness and comfort. Therefore, also, we must confess ourselves children of God, for by this name we deeply touch our God, since there is not a sweeter sound to the father than the voice of the child.—Martin Luther.
