¹⁴ We must no longer be children, tossed to and fro and blown about by every wind of doctrine by people’s trickery, by their craftiness in deceitful scheming;^(A)

⁹ Do not be carried away by all kinds of strange teachings, for it is good for the heart to be strengthened by grace, not by regulations about food,^[a] which have not benefited those who observe them.^(A)

²⁰ Brothers and sisters, do not be children in your thinking; rather, be infants in evil, but in thinking be adults.^(A)

Final Instructions

¹⁷ I urge you, brothers and sisters, to keep an eye on those who create dissensions and hindrances, in opposition to the teaching that you have learned; avoid them.^{(A) 18} For such people do not serve our Lord Christ but their own appetites,^[a] and by smooth talk and flattery they deceive the hearts of the simple-minded.^(B)

Testing the Spirits

4 Beloved, do not believe every spirit, but test the spirits to see whether they are from God, for many false prophets have gone out into the world.^(A)

⁶ But ask in faith, never doubting, for the one who doubts is like a wave of the sea, driven and tossed by the wind.^(A)

False Prophets and Their Punishment

2 But false prophets also arose among the people, just as there will be false teachers among you, who will secretly bring in destructive opinions. They will even deny the Master who bought them—bringing swift destruction on themselves.^{(A) 2} Even so, many will follow their debaucheries, and because of these teachers^[a] the way of truth will be maligned. ³ And in their greed they will exploit you with deceptive words. Their condemnation, pronounced against them long ago, has not been idle, and their destruction is not asleep.^(B)

¹² For though by this time you ought to be teachers, you need someone to teach you again the basic elements of the oracles of God. You need milk, not solid food,^{(A) 13} for everyone who lives on milk, being still an infant, is unskilled in the word of righteousness. ¹⁴ But solid food is for the mature, for those whose faculties have been trained by practice to distinguish good from evil.^(B)

¹⁷ For we are not peddlers of God’s word like so many,^[a] but as persons of sincerity, as persons sent from God, we are speaking in Christ before God.^(A)

¹¹ put on the whole armor of God, so that you may be able to stand against the wiles of the devil,
