In 1740 Edwards preached a sermon devoted exclusively to the children in the congregation, those up to age 14. He simplified his language but it is the same theologically rich vision of the loveliness of God.
The bulk of the sermon lists reasons why children should love Jesus. Here is the first.
There is no love so great and so wonderful as that which is in the heart of Christ. He is one that delights in mercy; he is ready to pity those that are in suffering and sorrowful circumstances; one that delights in the happiness of his creatures. The love and grace that Christ has manifested does as much exceed all that which is in this world as the sun is brighter than a candle. Parents are often full of kindness towards their children, but that is no kindness like Jesus Christ's. . . .--Jonathan Edwards, 'Children Ought to Love the Lord Jesus Christ,' in Works, Yale ed., 22:171-72
Everything that is lovely in God is in him, and everything that is or can be lovely in any man is in him: for he is man as well as God, and he is the holiest, meekest, most humble, and every way the most excellent man that ever was.
