Why can't the physical/religious man understand secrets of God's kingdom like the spiritual man?

the spiritual man shouldn't give a fuck what any godtards bleat on about

The physical man believes himself to be purely physical and separate from the creator thus believing himself incapable of knowledge of God.

The spiritual man knows there are no humans, plants, and animals. Only God manifesting infinite size, shape and abilities in the heavens and the earth,and our bodies with a mind complex enough to retain separatist beliefs and thus have free will. Spiritualist return the gift of free will for the will of God to be done with knowledge that all will be reveled to the physical mind in due time.

What do you mean " no humans plants animals"? Is God dreaming? I don't mean this sarcastically, everything in our dreams suddenly proves to be illusionary when we wake up?

tie a man's hands and feet can he neither stand nor walk

most religious people walk blindly thru spirituality and never work on themselves. they are followers, not leaders.

Right and as foretold they follow whatever religious philosophy a clergyman sells that's appealing to the market;
"Therefore Jesus said again: “Most truly I say to YOU, I am the door of the sheep.  All those that have come in place of me are thieves and plunderers; but the sheep have not listened to them.  I am the door; whoever enters through me will be saved, and he will go in and out and find pasturage.  The thief does not come unless it is to steal and slay and destroy. I have come that they might have life and might have it in abundance.  I am the fine shepherd; the fine shepherd surrenders his soul in behalf of the sheep.  The hired man, who is no shepherd and to whom the sheep do not belong as his own, beholds the wolf coming and abandons the sheep and flees—and the wolf snatches them and scatters them—  because he is a hired man and does not care for the sheep.  I am the fine shepherd, and I know my sheep and my sheep know me,  just as the Father knows me and I know the Father; and I surrender my soul in behalf of the sheep." Jo10:7

Charity and such are spiritual gifts from God, a physical man is interested in moving things around (more or less emotion free events/tasks)

Right the truth from Jehovah is free;
". And who is adequately qualified for these things? [We are;] for we are not peddlers of the word of God as many men are, but as out of sincerity, yes, as sent from God, under God’s view, in company with Christ, we are speaking." 2Cor2:17

religious connotes adherence to law and dogma which applied to genuine spiritual pursuits are detrimental

Spiritual discernment/true wisdom is a gift from God.

The physical/religious man is the natural/letter of the law rather than spirit of the law focused man, missing the essence of the Holy Spirit - insight into the ways and mind of God.

Little wonder God has no use for man's religions;
"There exists a way that is upright before a man, but the ways of death are the end of it afterward." Pr14:12
