十九节说到圣徒、神的家和神的国。圣徒是个别的；神的家是团体的，其结果乃是神的国。没有家，就不可能有国。首先，我们是个别的圣徒；然后，就团体说，我们是神的家，结果就是神的国。所以，我们有基督徒生活个别的一面，也有神的家和神的国团体的一面。
为甚么使徒保罗在十九节先题神的国后题神的家？保罗在这里的思想是论到我们从前作外人和寄居者的身分。外人和寄居的，是与国有关，而不是与家有关。凡在这个国家的外人，不是就着家而言是外人，乃是就着国而言是外人。因为外人和寄居的是指一个国家的外国人，而不是指一个家庭的外人，所以保罗先题国度。保罗在本节主要的思想，乃是在神国里的公民权。然而国度是由许多家庭组成的。为这缘故，保罗也题到神的家。
十九节有一个很亲密的思想，可见于“同国”一辞。我们原是未得救的外邦人，远离神和以色列国民，但现今我们与圣徒有了亲密的关系。我们是圣徒同国之民，是神家里的亲人。在同国的公民中间，有一种亲密存在，但这种亲密不能与家中的亲人相比。犹太人和外邦人不仅是同国的国民，也是同一家的亲人。我们需要亲密的把圣徒看为我们的亲人。我们是神家里的人不能只是道理，也必须是我们的经历。在宇宙中神只有一个家；不论我们的背景如何，我们这些圣徒都是神惟一宇宙家庭的亲人，所有的圣徒都是我们的亲人。不要轻看这件事，要把这事当作教会重要的一面来认真考量。在神的家中我们有何等亲密的关系！

The Saints, The House of God and Kingdom of God — Eph. 2:19
Verse 19 speaks of the saints, the house of God and the kingdom of God. The saints are individuals, but the house of God is corporate and results in the kingdom of God. If there were no house, there could be no kingdom. Firstly we are saints, individuals. Then, corporately, we are the house of God resulting in the kingdom of God. Therefore, we have both the individual aspect of the Christian life and the corporate aspect in the house of God and the kingdom of God.
In verse 19 why does the Apostle Paul refer to the kingdom of God before the house of God? Paul’s thought here concerns our former status as strangers and sojourners. Strangers and sojourners are related to a kingdom, not to a household. Those who are aliens in this country are not aliens in relation to a family, but in relation to the nation. Because strangers and sojourners are aliens to kingdoms, not to families, Paul mentions the kingdom first. In this verse Paul’s main concept is that of citizenship in God’s kingdom. The kingdom, however, is composed of families. For this reason, Paul also mentions the household of God, that is, the family of God.
In verse 19 there is the thought of intimacy, seen in the term fellow-citizens. As unsaved Gentiles, we once were far off from God and the commonwealth of Israel, but now we have an intimate relationship with the saints. We are fellow-citizens of the saints and members of God’s household. The Jews and the Gentiles are not only citizens of the same kingdom, but also folks of the same family. We need to regard the saints in an intimate way as our folks. Being members of the family of God must not only be our doctrine, but also our experience. In the universe God has just one household, one family. No matter what our background may be, as believers we all are members of God’s unique universal family, and all the saints are our folks. Do not take this matter lightly, but consider it seriously as an important aspect of the church. What an intimate relationship we have in the household of God!
