Thanks all, I almost understand now, the one aspect left for me to understand, is why the saints would have such supernatural qualifications as to be able to hear individuals prayers on earth
Christ is true God and true man. He's not "half" one, or "half" the other, but both, without confusion (for if there were confusion, if He were not "two natures" but "one nature", then we could no longer justly claim He was fully
both.) As such, His humanity is overflowing with divine grace, and itself takes on "Godly" qualities, without of course ceasing to be truly human. This is particularly so after His Ressurection, for by His own decision prior to this He humbled Himself and did not manifest all of these "God-Man" qualities (hence, being able to taste suffering, even death.) This is the great "kenosis" or "self-emptying" spoken of by St.Paul (Philippians 2:6-7).
Well, Orthodox Christians are those who are struggling in the Church Christ founded - and they are those who are being assimilated into Christ. This begins with their Holy Baptism, but the increase of this assimilation is a never ending reality, if the person perseveres. This includes the assimilation of those "God-Man" qualities. This is why those the Church liturgically commemorates and publically recognizes as "saints" (holy ones) manifested extraordinary capacities even before reposing in the Lord. They typically manifested varying degrees of clairvoyance, able to read the hearts of others - they often entered the state of "theoria" (vision of God) in which the laws of the physical world simply stopped applying to them, or at least in all of their awful corrosiveness (like St.Seraphim of Sarov who prayed for a thousand days and nights, straight upon a rock in the woods, or St.Herman of Alaska who was able to physically do and endure things simply impossible for a man of his size and age.) In addition, even the relics of these Saints, manifest inexplicable qualities - they do not putrify or decompose like the bodies of most people, sometimes not even for centuries on end, and it's not unusual for them to in fact smell like fragrant myrh, and even gush myrh resin with healing properties.
The point is these men, being participants of the Risen Saviour, are themselves glorifed by their Lord. Thus, if they've gone to reign with Him in His Kingdom, it is perfectly "reasonable" that they have capacities for hearing and being present to people beyond anything we can fathom. To doubt this, would be much like doubting just how
it can be that the Lord Jesus Christ, can be truly present under the appearances of bread and wine in so many places, at so many times, in so much quantity? Has Christ increased physically? At most, He is 6ft tall and of average (if sturdy) build, if we use the Iconographic tradition and the Holy Shroud (currently in Turin - it was once in Hagia Sophia before the Crusaders looted it) as a guide. It's like the paradoxical question - in the Divine Liturgy, is Golgotha being repeated, or are we going to Golgotha? For the Holy Oblation occurs in the Eucharist (and there are many such celebrations at any given time, in many places), yet we know as a dogmatic certainty that Christ suffers no more, and that He died but once.
18 And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth. (St.Matthew 28:18)
16 I Jesus have sent mine angel to testify unto you these things in the churches. I am the root and the offspring of David, and the bright and morning star. (Apocalypse 22:16)
26 And he that overcometh, and keepeth my works unto the end, to him will I give power over the nations:
27 And he shall rule them with a rod of iron; as the vessels of a potter shall they be broken to shivers: even as I received of my Father.
28 And I will give him the morning star. (Apocalypse 2:26-28)
Truly, God's saints (above all those who are glorified both in heaven and
on earth because of their great sanctity) reign with Him.
