1 John 4:2-10

By this you know and recognize the Spirit of God: every spirit that acknowledges and confesses [the fact] that Jesus Christ has [actually] come in the flesh [as a man] is from God [God is its source]; and every spirit that does not confess Jesus [acknowledging that He has come in the flesh, but would deny any of the Son’s true nature] is not of God; this is the spirit of the antichrist, which you have heard is coming, and is now already in the world. Little children (believers, dear ones), you are of God and you belong to Him and have [already] overcome them [the agents of the antichrist]; because He who is in you is greater than he (Satan) who is in the world [of sinful mankind]. They [who teach twisted doctrine] are of the world and belong to it; therefore they speak from the [viewpoint of the] world [with its immoral freedom and baseless theories—demanding compliance with their opinions and ridiculing the values of the upright], and the [gullible people of the] world listen closely and pay attention to them. We [who teach God’s word] are from God [energized by the Holy Spirit], and whoever knows God [through personal experience] listens to us [and has a deeper understanding of Him]. Whoever is not of God does not listen to us. By this we know [without any doubt] the spirit of truth [motivated by God] and the spirit of error [motivated by Satan]. Beloved, let us [unselfishly] love and seek the best for one another, for love is from God; and everyone who loves [others] is born of God and knows God [through personal experience]. The one who does not love has not become acquainted with God [does not and never did know Him], for God is love. [He is the originator of love, and it is an enduring attribute of His nature.] By this the love of God was displayed in us, in that God has sent His [One and] only begotten Son [the One who is truly unique, the only One of His kind] into the world so that we might live through Him. In this is love, not that we loved God, but that He loved us and sent His Son to be the propitiation [that is, the atoning sacrifice, and the satisfying offering] for our sins [fulfilling God’s requirement for justice against sin and placating His wrath].
