What is so indirect, that it could lead to falling away? Firstly Hebrews speaks about the evil HEART of unbelief, which puts emphasis on what people believe, and what their intents and thoughts are. In this way, it is the pretenses, ways that people only honor Him with their lips, and their departing from things that leads up unto their falling away beyond repentance. Not to mention the kind of behavior that Jezebel had as she attempted to condemn Jehu. Within these things, as with the bad report that the Israelites gave, when people fall away, they do actually blaspheme the Holy Spirit, by the way that they reject Him. One of the meanings of rejection, in loking at the makeup of the word, as through a morpheme, is in how there is only a repeating of what has already been projected, and not a progression. This obviously shows the blasphemy of the Holy Spirit, and the rejection of the Spirit of Jesus Christ, to be the unpardonable sin and the ways of the unprofitable servant. And this is the fruit of the harlot, of Babylon (Dianna), Jezebel, and Aphrodite, just as they are half and half. And so there is correlation between Babylon and people who only attempt to leave their future open to God's prosperity, but also decide to only follow Him in the present according to their own dictates. And this is true just as the harlot rides the beast, as I have given example before, as to someone riding on an animal and leading it with food tied onto a stick in front of it, whether or not the animal does or doesn't get the food. The doubleness of the harlot, as with this behavior, is the indirect substance of how someone can fall away beyond repentance. The greatest evil found in the unprofitable servant is that he doesn't even entertain that he is not being whole with God, just as Babylon fornicates, and therefore the whole entire subject of wholly seeking God, and or only seeking Him according to the dictates of one's heart and thoughts is completely buried away. This is what allows people to remain blind and deaf, as Jesus and Isaiah spoke about those who had unbelief, whom the LORD would also not heal, because it would be without their oneness in Him.

God Himself does not lead people, as with the example of the harlot riding the beast. And this is the substance of the night season, because God is fully hearing and answering the prayers of those who love Him. The only difference, as to why people are seeming to be without His presence and answerings in the night season, is that God is actually going before and behind them, and giving them the ability to open their mouths wide and wider. Just as these verses show:

Psalm 22:1-2
1 My God, My God, why have You forsaken Me?
Why are You so far from helping Me,
And from the words of My groaning?
2 O My God, I cry in the daytime, but You do not hear;
And in the night season, and am not silent.

Hebrews 5:7
when He had offered up prayers and supplications, with vehement cries and tears to Him who was able to save Him from death, and was heard because of His godly fear

Psalm 81:10
Open your mouth wide, and I will fill it.

The godly fear that Jesus had, just as He did have the fear of the LORD, as Isaiah 11 shows, is found in how Jesus still cried out to Him and opened His mouth wide so that God could fill it, even though He may have been in the night season, as Psalm 22 gives example of Him feeling as if the LORD didn't hear. And this is exactly the type of behavior that leads into entering in, just as God offers salvation to all, even though He already knows who will be saved and who won't be. And there is fulfillment in this, just as we still should fully and wholly seek God and open our mouths wide for Him to fill them, even though we don't have to, or even though we may think that the LORD's presence is not with us or near to us. The Bible does speak about the wickedness of people who say "The LORD does not see," and so when we open our mouths wide for Him to fill them, even though we may think He isn't answering us, we are actually waiting on the LORD, and when we are filled, as we pour ourselves out, to receive what is incorruptible and what is reserved for us that can not decay, rot, and become defiled, we shall have overcome. From every little thing, unto every large thing. In this is the fulfillment of what it means when Jesus said that to him who has more will be given, and to him who doesn't have, even what he does have will be taken away from him. Because what we do have is the knowledge and fear of God, by which we may be faithful, even though we pour ourselves out and go through the night seaons. But the truth about what we don't have, or that what the unprofitable don't have, is found in how we have to pour ourselves out concerning the things that can corrupt, to receive what can not corrupt. And thus even if we do not go through the night seaons, and even if we do not pour ourselves out, we really do not have anything that is good or everlasting, and thus it is counting as nothing. But it is the knowledge of God, that is also with His talent that He gives, which is the witness that we have from Him, by which He gives us His Promises, which include the all things from Him that shall never pass away. And thus those who wait for Him will not be ashamed, even as Jesus despised the shame of the cross for the joy that was set before Him, and when the morning comes there shall be fulfillment as we may even mount up on eagle's wings, as God does more than just give us gifts, He also gives us rewards, knowing again, that we should not just leave and go do something else, but that we should entreat the LORD, serve Him, and more.
