7 Bible Verses about Apostasy, How To Avoid

But evil people and impostors will go from bad to worse [in their behavior], deceiving people and being deceived by them. But you should continue [to believe and practice] what you have learned and been convinced of, knowing those from whom you learned it. [Note: These persons would include Lois and Eunice (See 1:5), as well as Paul himself]. And [remember] that, from childhood, you have known the sacred Scriptures which are able to make you wise [enough] to be saved through faith in Christ Jesus.read more.
All Scripture is inspired by God [Note: Literally, this word means "breathed out by God"] and is useful for teaching [truth], rebuking [wrongdoing], correcting [error] and for providing instruction [i.e., training] on how to live right, so that the man of God will be thoroughly equipped for [doing] every good deed.

And for this very reason, you people should make every effort to develop goodness along with your faith, and knowledge along with your goodness, and self-control along with your knowledge, and endurance along with your self-control, and godliness along with your endurance, and brotherly kindness along with your godliness, and with your brotherly kindness, develop love.read more.
For if you people have a lot of these [qualities] they will keep you from being unproductive and unfruitful in the knowledge of our Lord Jesus Christ. But, anyone who lacks these qualities is [spiritually] blind and shortsighted, and has forgotten that he has been cleansed [i.e., forgiven] of his past sins. So, brothers, be diligent to make sure of your calling and election [i.e., of your status as being selected by God], for when you do, you will never stumble [and fall away from God]. For in this way, you will be provided with a rich welcome into the never ending kingdom of our Lord and Savior Jesus Christ [i.e., in heaven].

[Because] I know that after I am gone [from here] there will be vicious wolves [i.e., ravaging false teachers] who will come in among you, and they will not spare the flock [i.e., the congregation]. [Indeed, even] from among your own selves [i.e., the body of elders there in Ephesus] some men will arise and, by speaking false things, they will lead away the disciples, [influencing them] to follow them. So, be very watchful, and remember that for three years I never stopped warning every one of you [about such matters] both night and day with tears [in my eyes].

Loved ones, do not believe [the message of] every spirit [i.e., every person claiming to be a teacher], but test the spirits [i.e., require proof that they and their message are genuine] to see whether they represent God [or not], because many false prophets have begun circulating throughout the world. Here is how to know [who is speaking from] the Holy Spirit of God: Every spirit [i.e., person] who proclaims that Jesus Christ has come [to earth] in a physical body is [speaking] from God. [See I Cor. 12:3]. But every spirit who does not proclaim [this truth about] Jesus is not [speaking] from God. And this [person] represents the spirit of the antichrist [See 2:18-22; II John 7], whom you have heard would come. Well, now he is already here!read more.
[But], you people are [followers] of God, little children [i.e., dear ones], and you have overcome them [i.e., these false teachers] because He who is in your lives [i.e., the Holy Spirit, See 3:24] is greater [i.e., more powerful] than he who is in [i.e., dominates] the world [i.e., Satan. See II Cor. 4:4]. These [false teachers] are part of the world, so [naturally] they speak [a message endorsed] by the world and the world listens to them. We [who preach the true Gospel] represent God; the person who knows God listens to our message; the one who does not belong to God does not listen to us. This is how we can know [the difference between those speaking by] the Holy Spirit of truth and [those speaking by] the spirit of [Satan's] error.

[This is to be done] until we all [eventually] arrive at unity of the faith and full knowledge of the Son of God; at complete [spiritual] maturity; at the [full] height of Christ's [spiritual] stature. Then we will no longer be [spiritual] babies, tossed back and forth [by waves], and blown around by every wind of [false] teaching, [deceived] by the clever trickery of people using deceptive schemes. But [instead], we should speak [and practice] truth in a loving way, so that we can, in all respects, grow up [spiritually] into [union with] Christ, who is the head [i.e., of His body, the church].read more.
From Him all [members of] the body are properly joined together by every supporting ligament, as each part contributes to the growth of the body and builds itself up through [mutual] love.

Finally, be [spiritually] strong in the Lord and in His mighty power. You people should put on the full armor of God, so that you will be able to withstand the devil's schemes. For our struggle is not [actually] against human beings, but against rulers and authorities and leaders of this world's darkness, and against the spiritual forces of evil in the heavenly realms. [Note: "Heavenly realms" here refers to the struggle against Satanic powers which permeates life around us].read more.
Therefore, put on the full armor of God, so that you can withstand [the devil, See verse 11] when the evil day comes. And, after you have done everything you can, still remain standing firm [in the faith]. So, you people should stand firm [in the faith], with the belt of truth firmly buckled around you, and with the "flack jacket" of righteousness on your chest. And put on your shoes, ready to [go and] spread the Gospel of peace. And along with everything else, take up the shield of faith, with which you will be able to extinguish all the fire-tipped arrows of the evil one. And take the helmet of salvation, and the sword of the Holy Spirit, which is God's word. [Then] offer all kinds of prayers and requests in [harmony with] the Holy Spirit at all times, and be alert constantly in making requests for all the saints [i.e., God's holy people]. And [also pray] for me to be given boldness of speech in opening my mouth to make known the secret plan of the Gospel, for which I am an ambassador in prison. [And pray] that I may be able to proclaim the Gospel boldly, as I ought to.

Preach the [Gospel] message; be prepared [to do it both] when it is convenient and when it is inconvenient; reprove [i.e., convince people of their wrongdoing], rebuke [i.e., convict people of their sin], and exhort [i.e., urge people to act], with great patience and teaching.
