951. 22:14 Blessed are those who do His commandments, that they may have their power in the tree of life, and may enter through the gates into the city. This symbolically means that eternal happiness awaits those who live in accordance with the Lord's commandments, in order that through love, and in His New Church through concepts of Him, they may be in the Lord and have the Lord in them.

The blessed symbolize people who possess the felicity of eternal life (nos. 639, 852, 944). To do the Lord's commandments means, symbolically, to live in accordance with His commandments. That they may have their power in the tree of life means, symbolically, in order that through love, that is, for the Lord's sake, they may be in the Lord and have the Lord in them, which we explain below. To enter through the gates into the city means, symbolically, that they may be in the Lord's New Church through concepts of Him. The gates in the wall of the New Jerusalem symbolize concepts of goodness and truth from the Word (nos. 899, 900, 922), and because each gate consisted of a single pearl, the gates symbolize principally concepts of the Lord (no. 916). The city, that is, Jerusalem, symbolizes the New Church together with its doctrine (nos. 879, 880).

[2] That they may have their power in the tree of life means, symbolically, in order that through love, that is, for the Lord's sake, they may be in the Lord and have the Lord in them, because the tree of life symbolizes the Lord in respect to His Divine love (nos. 89, 933). And the power in that tree symbolizes power from the Lord, because they are in the Lord and have the Lord in them. The symbolic meaning of this is similar to that of the declaration that they will reign with the Lord (nos. 284, 849).

That people who are in the Lord and have the Lord in them possess all the power needed to be able to do whatever they will, the Lord Himself says in John:

He who abides in Me, and I in him, bears much fruit; for without Me you can do nothing... If you abide in Me, and My words abide in you, you will ask what you desire, and it shall be done for you. (John 15:5, 7)

Something similar is said about this power in Matthew 7:7, Mark 11:24, Luke 11:9-10. Indeed, we read in Matthew:

Jesus... said..., ."..if you have faith..., ...if you say to this mountain, 'Raise yourself up... cast yourself into the sea,' it will be done. (Indeed,) everything you ask..., believing, you will receive." (Matthew 21:21-22)

This describes the power those people have who are in the Lord. They do not wish for and so do not ask for anything that does not come from the Lord; and whatever they wish for and ask from the Lord, this comes to pass, for the Lord says, "without Me you can do nothing. Abide in Me, and I in you." Such is the power that angels in heaven have, that they have only to wish for something in order to obtain it. But still they wish only for things that may be of useful service, wishing this as though of themselves, but in fact from the Lord.
