Some of you spend Christmas day surrounded by your families. Possibly you have a large family—ten or twelve are at home on that day, with a grandchild or two. I will tell you what your greatest joy is on that day: it is to see the happiness of your children and to mark how they enjoy what you provide for them. They are only little children, some of them, creeping about on the floor, but they please you because they are so pleased themselves. The crow of a little child delights your heart, for it gives us joy to behold joy in those we love.
Suppose your sons and daughters all come marching in on Christmas day in a very gloomy state of mind—cold, loveless, joyless. Suppose they do not enjoy anything, but grumble at you and at one another. You would be quite sad and wish the day to be soon over and never come again for the next seven years. Thus, in an illustration, we see that our heavenly Father delights in the delight of His children and is glad to see them grateful and happy, and acting as children should do toward such a Parent.
– Charles Spurgeon
