We find true unity in Bible truth, humbly believing in our Heavenly Father and Jesus. “Sanctify them by Your truth. Your word is truth. As You sent Me into the world, I also have sent them into the world. And for their sakes I sanctify Myself, that they also may be sanctified by the truth. I do not pray for these alone, but also for those who will believe in Me through their word; that they all may be one, as You, Father, are in Me, and I in You; that they also may be one in Us, that the world may believe that You sent Me” (John 17:17-21).
We must follow Jesus alone. Jesus is our only Shepherd, and He has not appointed anyone on earth to take His place. “And other sheep I have which are not of this fold; them also I must bring, and they will hear My voice; and there will be one flock and one shepherd” (John 10:16). “My sheep hear My voice, and I know them, and they follow Me” (John 10:27). “Therefore whoever hears these sayings of Mine, and does them, I will liken him to a wise man who built his house on the rock…. But everyone who hears these sayings of Mine, and does not do them, will be like a foolish man who built his house on the sand” (Matthew 7:24, 26). “If you love Me, keep My commandments” (John 14:15).
We are chosen out of the world by Jesus. “If you were of the world, the world would love its own. Yet because you are not of the world, but I chose you out of the world, therefore the world hates you” (John 15:19).
We are called by God to leave non-Biblical teachings, non-Biblical worship days, and non-Biblical traditions. “Depart! Depart! Go out from there, touch no unclean thing; go out from the midst of her, be clean, you who bear the vessels of the Lord” (Isaiah 52:11). “Flee from the midst of Babylon, and every one save his life! Do not be cut off in her iniquity, for this is the time of the Lord’s vengeance; He shall recompense her” (Jeremiah 51:6). “And I heard another voice from heaven saying, ‘Come out of her, my people, lest you share in her sins, and lest you receive of her plagues’” (Revelation 18:4).
Also prayerfully study 1 Peter 2:9 and 1 John 2:15-17.
