Abide in the doctrine of Christ

We must be fervent in what we have believed and abide in the doctrine of Christ and the apostles, and the big question is: What is the doctrine of Christ? All the doctrine of Christ is found in His Word: The Bible. And in it is all we need to live a correct Christian life, we do not need another way or a new revelation given by a person, His Word is enough and in it we sustain and remain.

The Bible talks about staying in the doctrine of Christ and it is John when he says:

9 Anyone who runs ahead and does not continue in the teaching of Christ does not have God; whoever continues in the teaching has both the Father and the Son.

10 If anyone comes to you and does not bring this teaching, do not take them into your house or welcome them.

11 Anyone who welcomes them shares in their wicked work.

2 John 1:9-11

God has called us to be persevering in the doctrine of His Word, and this perseverance is achieved by reading and studying the Scriptures, remember that one time Jesus said: “Search the Sacred Scriptures.” It is our duty to study the Bible, since through it we realize what is God’s good will for us, which is holy and perfect.

On the other hand, there is the part of those people who come to us teaching us a doctrine totally different from the one that is expressed in the Bible, and the apostles make many warnings about this and we must take them to avoid falling into the falsehoods of this century.

We should never be part of the erroneous teachings, but let us remember something important, and is that the only way for us to realize when the doctrines are wrong is by being faithful scholars of what the Bible says.

I urge you to study the Word of God so that we are not deceived by false doctrines.

The importance of remaining grounded in the doctrine of Christ cannot be overstated, especially in a time when so many voices rise with teachings that sound appealing but lack biblical foundation. Throughout history, the church has faced countless attempts to distort or add to the message of Scripture, yet the call of God has always been the same: “Hold fast to the pattern of sound teaching.” The truth of God does not evolve with culture, nor does it bend to trends or philosophies of the modern age. His Word is eternal, unchangeable, and fully sufficient to guide, correct, and sustain us. When believers anchor themselves deeply in Scripture, they develop discernment—an ability to recognize what is true and what deviates from the teachings of Christ. This discernment is a precious gift in a world saturated with deception.

John’s warning is not merely theoretical; it is profoundly practical. There will always be individuals who present themselves as spiritual guides, prophets, or enlightened teachers, yet their message is disconnected from the apostolic truth. They may speak with passion, eloquence, or charisma, but if their doctrine does not align with Christ’s teaching, they are to be rejected. The apostle’s instruction not to welcome such people is not a call to hostility, but a call to spiritual protection. To give hospitality or approval to false teachers is to become complicit in their deception, enabling them to spread teachings that harm the church. True love for God includes protecting the purity of His truth, just as a shepherd protects the flock from wolves. Our loyalty must always be first to Christ, then to His Word, and only then to those who teach according to it.

Persevering in sound doctrine is not merely an intellectual exercise; it is a spiritual safeguard. When we immerse ourselves in the Scriptures, the Holy Spirit enlightens our understanding, strengthens our convictions, and aligns our hearts with the will of God. This steady commitment shapes our character, influences our decisions, and guards us from subtle distortions that can lead us astray. The more we grow in the knowledge of truth, the harder it becomes for error to deceive us. Let us, therefore, be diligent students of the Word, seeking not only to understand it but to live it out daily. In doing so, we walk in the light of Christ, remain anchored to the faith once delivered to the saints, and honor the God who entrusted His truth to us. May the Lord keep us firm, faithful, and unmovable in His holy doctrine.
