There are mysteries in Christianity, things which have to be revealed, things which you cannot just figure out.

Why do you speak in parables? Jesus’ disciples
asked, Mtt 13:10.

The truth is, just as the occult teaches, that not everyone deserves to know all of the secrets of eternal life!

“He answered them, “To you it is given to know the mysteries of the Kingdom of Heaven, but it is not given to them.””
Mtt 13:11 WEB

If you have any ears you should listen to these things, Mtt 13:9. The occult handles such things through not telling most people the core beliefs of their religion. In the gospel these things are handled in a different way. We are supposed to tell everyone what they need to know. Tell them, whether they will listen or not, Ezek 2:5. Even so, they truth is that people filter themselves out from life.

“Now the natural man doesn’t receive the things of God’s Spirit, for they are foolishness to him, and he can’t know them, because they are spiritually discerned.”
1Cor 2:14 WEB

We declare openly the very mysteries of life.

The One, Jesus the Christ, who created all life.

“3 All things were made through him. Without him was not anything made that has been made. 4 In him was life, and the life was the light of men.”
Jn 1:3-4 WEB

The very wisdom of the ages we declare.

“6 We speak wisdom, however, among those who are full grown [teleios in Greek]; yet a wisdom not of this world, nor of the rulers of this world, who are coming to nothing. 7 But we speak God’s wisdom in a mystery, the wisdom that has been hidden, which God foreordained before the worlds for our glory, ”
1Cor 2:6-7 WEB emphasis added

If you have some understanding of eternal things,

God will give you even more.

“For whoever has, to him will be given, and he will have abundance,”
Mtt 13:12a WEB

You might compare this to our muscles. If you use your muscles they will grow and increase in strength. On the other hand,

“but whoever doesn’t have, from him will be taken away even that which he has.”
Mtt 13:12b WEB

It is a use it or lose it sort of things. Similarly, if you never use your muscles, they can atrophy to the point you cannot use them at all.

If we decide we really don’t like this, don’t really
want to do this, we CUT OURSELVES off,
from further understanding.

“14 … ‘By hearing you will hear,
And will in no way understand;
Seeing you will see,
And will in no way perceive:
15 For this people’s heart has grown callous,
Their ears are dull of hearing,
They have closed their eyes;
Or else perhaps they might perceive with their eyes,
Hear with their ears,
Understand with their heart,
And should turn again;
And I would heal them.’”
Mtt 13:14-15 WEB

If this is our case, our understanding
stops right there!
