303. In the celestial sense, this commandment means conjunction with the Lord, followed by peace, because of protection from hell. For the Sabbath signifies rest, and in this highest sense, peace; therefore the Lord is called the Prince of Peace, and He also calls Himself "Peace," as is evident from the following passages:
Unto us a Child is born, unto us a Son is given; and the government shall be upon His shoulders; and His name shall be called Wonderful, Counselor, God, Mighty, Father of eternity, Prince of Peace. Of the increase of His government and peace there shall be no end (Isa. 9:6, 7). Jesus said, Peace I leave with you, My peace I give unto you (John 14:27). Jesus said, These things have I spoken unto you that in Me ye may have peace (John 16:33). How beautiful upon the mountains are the feet of him that bringeth good tidings, that publisheth peace; saying, Thy King reigneth (Isa. 52:7). Jehovah will deliver my soul in peace (Ps. 55:18). Jehovah's work is peace; and the labor of righteousness rest and security forever that My people may abide in a habitation of peace, and in tents of security, in quiet resting-places (Isa. 32:17. 18). Jesus said to the seventy whom He sent forth, Into whatsoever house ye enter, first say, Peace be to this house; and if a son of peace be there, your peace shall rest upon him (Luke 10:6, 8; Matt. 10:12-14). Jehovah will speak peace unto His people. Righteousness and peace have kissed each other (Ps. 85:8, 10). When the Lord Himself appeared to His disciples, He said, Peace be unto you (John 20:19, 21, 28). Moreover, the state of peace into which men are to come from the Lord is treated of in Isa. 65, 66 and elsewhere; and those will come into that state, who are received into the New Church which the Lord is establishing at this day. What peace is in its essence, which is the peace in which the angels of heaven and those who are in the Lord are, may be seen in the work on Heaven and Hell (n. 284-290). From all this it is also evident why the Lord called Himself "Lord of the Sabbath," that is, of rest and peace.
