Luke 10:20

Because your names are written in heaven - This form of speech is taken from the ancient custom of writing the names of all the citizens in a public register, that the several families might be known, and the inheritances properly preserved. This custom is still observed even in these kingdoms, though not particularly noticed. Every child that is born in the land is ordered to be registered, with the names of its parents, and the time when born, baptized, or registered; and this register is generally kept in the parish church, or in some public place of safety. Such a register as this is called in Philippians 4:3; Revelation 3:5, etc., the book of life, i.e. the book or register where the persons were enrolled as they came into life. It appears also probable, that when any person died, or behaved improperly, his name was sought out and erased from the book, to prevent any confusion that might happen in consequence of improper persons laying claim to an estate, and to cut off the unworthy from the rights and privileges of the peaceable, upright citizens. To this custom of blotting the names of deceased and disorderly persons out of the public registers, there appear to be allusions, Exodus 32:32, where see the note; and Revelation 3:5; Deuteronomy 9:14; Deuteronomy 25:19; Deuteronomy 29:20; 2 Kings 14:27; Psalm 69:28; Psalm 109:13, and in other places.

Rather rejoice ... - Though it was an honor to work miracles, though it is an honor to be endowed with talents, and influence, and learning, yet it is a subject of "chief" joy that we are numbered among the people of God, and have a title to everlasting life.

Names are written in heaven - The names of citizens of a city or state were accustomed to be written in a book or register, from which they were blotted out when they became unworthy, or forfeited the favor of their country. Compare Psalm 69:28; Exodus 32:32; Deuteronomy 9:14; Revelation 3:5. That their "names were written in heaven," means that they were "citizens" of heaven; that they were friends of God and "approved" by him, and would be permitted to dwell with him. This was of far more value than all "earthly" honor, power, or wealth, and "in" this people should rejoice more than in eminent endowments of influence, learning, talents, or possessions.

10:20 Rejoice not so much that the devils are subject to you, as that your names are written in heaven - Reader, so is thine, if thou art a true, believer. God grant it may never be blotted out!
