Romans 16:17 I appeal to you, brothers, to watch out for those who cause divisions and create obstacles contrary to the doctrine that you have been taught; avoid them. For such persons do not serve our Lord Christ, but their own appetites, and by smooth talk and flattery they deceive the hearts of the naive. For your obedience is known to all, so that I rejoice over you, but I want you to be wise as to what is good and innocent as to what is evil. The God of peace will soon crush Satan under your feet. The grace of our Lord Jesus Christ be with you.
Acts 15:24 Since we have heard that some persons have gone out from us and troubled you with words, unsettling your minds
1 Corinthians 3:3 for you are still of the flesh. For while there is jealousy and strife among you, are you not of the flesh and behaving only in a human way?
Jude 1:19 It is these who cause divisions, worldly people, devoid of the Spirit.
Galatians 2:4 Yet because of false brothers secretly brought in—who slipped in to spy out our freedom that we have in Christ Jesus, so that they might bring us into slavery—
Philippians 3:2-3 Look out for the dogs, look out for the evildoers
Colossians 2:8 See to it that no one takes you captive by philosophy and empty deceit, according to human tradition, according to the elemental spirits of the world, and not according to Christ.
2 Peter 2:1-2 But false prophets also arose among the people, just as there will be false teachers among you, who will secretly bring in destructive heresies,
2 John 1:7-10 For many deceivers have gone out into the world
Watch out for those who cause division and create obstacles. Watch out for the dogs and evildoers. Watch out for empty philosophy, human tradition, and deceit. Watch out for false prophets and false teachers. Watch out for deceivers. It is often overlooked, but good to know and realize all of the verses in the bible that speak about being careful not to be drawn away from Christ by the craftiness of man. These are but a few and they are there for a reason so that we might walk in the fullness of Jesus Christ. It is one thing to say “watch out”, and an entirely different aspect to be able to recognize it. If there is one thing that limits the ability to recognize “watch out” signals it is the lack of God’s Word in our daily lives. When His Word is neglected, the clarity of these “watch out” signals becomes blurred and believed as truth or true enough that is possibly true. When this happens we are at the hands of Satan and not of God. Be in His Word, study it, hunger and thirst for it, and meditate on it. Know what you believe and why you believe it. Know there are those who will pervert the Word of God and draw many away from the blessings of honoring, following, obeying, trusting, and hoping in Jesus Christ alone.
