1 Παρακαλῶ οὖν ὑμᾶς, ἀδελφοί, διὰ τῶν οἰκτιρμῶν τοῦ θεοῦ παραστῆσαι τὰ σώματα ὑμῶν θυσίαν ζῶσαν ἁγίαν εὐάρεστον τῷ θεῷ, τὴν λογικὴν λατρείαν ὑμῶν· 2 καὶ μὴ συσχηματίζεσθε τῷ αἰῶνι τούτῳ, ἀλλὰ μεταμορφοῦσθε τῇ ἀνακαινώσει τοῦ νοὸς εἰς τὸ δοκιμάζειν ὑμᾶς τί τὸ θέλημα τοῦ θεοῦ, τὸ ἀγαθὸν καὶ εὐάρεστον καὶ τέλειον. Romans 12:1-2 (NA28)
1 Therefore, I urge you brothers through the compassions of God to present your bodies as living, holy sacrifices, well pleasing to God, which is your spiritual service. 2 And do not be conformed to this age, but be transformed by the renewing of your mind that you may discern the will of God, that which is good and well pleasing and perfect. Romans 12:1-2 (translated from the NA28 Greek text)
Both the Apostle John and the Apostle Paul used light and darkness in analogies pertaining to spiritual life and spiritual death. For instance, in John 1:4, 5 the Apostle says, “ἐν αὐτῷ ζωὴ ἦν, καὶ ἡ ζωὴ ἦν τὸ φῶς τῶν ἀνθρώπων· καὶ τὸ φῶς ἐν τῇ σκοτίᾳ φαίνει, καὶ ἡ σκοτία αὐτὸ οὐ κατέλαβεν.” Or, “In Him was life, and the life was the light of men; and the light shines in the darkness and the darkness does not grasp it.” In order to lay the foundation for this discussion on understanding the Lord’s will, it is imperative that we first understand what is being said in these two verses. First, the “Him” in v4 refers back to ὁ λόγος or “the Word” from v1. This is, of course, our Lord Jesus Christ. In v4, we learn that in Him was ζωὴ or zōē, “life.” This ζωὴ is not simply the life we all have here and now, but was φῶς τῶν ἀνθρώπων or the “the light of men.” What does that mean? This light comes from God and brings to this dark world true knowledge, moral purity, and the light that shows the very presence of God. Finally, notice that this light shines into the darkness, but the darkness does not “receive, admit, or grasp” it. Those who understand the will of God are in His light. Those who do not are in darkness.
