The apostle Paul warns Christians in general not to accept everything and anything, and he was absolutely right J

Ephesians 4: 14  that we should no longer be children, tossed to and fro and carried about with every wind of doctrine, by the trickery of men, in the cunning craftiness of deceitful plotting,

Sometimes we can be so deeply rooted in our way of thinking that we will make ourselves hermetic to the truth. When Paul spoke about " floating children ", he was talking about people who are not able to settle in their thoughts, who change their minds all the time, without probing what they hear.

It is just as harmful to accept anything as it is to be closed to everything.

1 Thessalonians 5: 21  Test all things; hold fast what is good.

The problem is that 60% of Christians today remain on their first revelation. To remain on one's first revelation means that one hears teachings that he adopts in his life, but which sometimes are not what the Bible says. 
Unfortunately, the problem is not new, because Paul, as a teacher, was already confronted with this kind of problem almost 2000 years ago.

So Paul says on the one hand not to remain children who will accept anything without thinking about it, but he also says that we have the potential to examine what we hear.

Another version of 1 Thessalonians 5: 20-22 says:  Do not scorn or reject gifts of prophecy or prophecies [spoken revelations—words of instruction or exhortation or warning]. 21 But test [a]all things carefully [so you can recognize what is good]. Hold firmly to that which is good. 22 Abstain from every form of evil [withdraw and keep away from it].

We therefore have the duty to examine, to test, that is, not to reject from the outset what we hear, as long as it is not obviously impregnated with evil.
Too many Christians miss out on blessings because they reject teachings that are consistent with what the Bible says simply because they are different from what they have heard so far.
Too much on one side will be as bad as too much on the other.
That is why it is important to act in a balanced way.

The first thing is not to reject, but to examine with the help of the Holy Spirit to guide me. If a teaching seems doubtful to you, but where you find nothing wrong with it in evidence, test it!
Examine it by projecting what will happen in your life if you put such a teaching into practice...
What are the consequences of such teaching?
What are the repercussions that can arise in my life and in the lives of others?
Are there any applications of this teaching that will prevent me from manifesting the image of God in my life?
Will this teaching help me to develop my humility?

These are the kinds of questions that are important to ask before rejecting what I hear.

When we are confronted with different ideas, different teachings, when we have not yet acquired 100% of the truth, there are two options for us:

    1°) I know the whole truth, in which case I have nothing to learn. I can therefore reject any teaching that is presented to me, because I consider that I have nothing more to learn. In this case I am perfect, because all the truth of God is in me.

    2°) I am aware that I still have to learn, so I do not reject everything that is presented to me because I do not want to miss a teaching that will help me to grow, to become a little more like God, to be love as He is love. Nevertheless, I remain very vigilant because I know that the devil uses false teachings to lose and make Christians sterile.

In a nutshell because we are in our quick teachings, it is important to be aware that I have to grow, I have to evolve; I still have a lot to learn about the person of God. It is also important to be aware that there are areas in which I may be wrong, because I do not have the right way of thinking.
To grow up I sometimes have to accept that I was wrong in a particular area.

So we must not accept everything without thinking, but examine, experience, test what we hear and not reject what does not generate evil in an obvious way.

See you soon.
