Do the saints pray in heaven? The book of Revelation tells us:

Revelation 5:8 And when he had taken the book, the four beasts and four
[and]
twenty elders fell down before the Lamb, having every one of them harps, and
golden vials full of odours, which are the PRAYERS OF SAINTS.

Revelation 8:3 And another angel came and stood at the altar, having a
golden
censer; and there was given unto him much incense, that he should offer [it]
with THE PRAYERS OF ALL SAINTS upon the golden altar which was before the
throne. 4 And the smoke of the incense, [which came] with the PRAYERS OF THE
SAINTS, ascended up before God out of the angel's hand.

Obviously they do pray, and as we saw in Hebrews we come to these saints,
who we
see intercede for us.

Is there more evidence that the Saints are aware of what is going on at
earth,
and do they ask for justice?:

Revelation 6:9 And when he had opened the fifth seal, I saw under the altar
the
souls of them that were slain for the word of God, and for the testimony
which
they held: 6:10 And they cried with a loud voice, saying, How long, O Lord,
holy
and true, dost thou not judge and avenge our blood on them that dwell on the
earth? Revelation 18:18 And cried when they saw the smoke of her burning,
saying, What [city is] like unto this great city! 18:19 And they cast dust
on
their heads, and cried, weeping and wailing, saying, Alas, alas, that great
city, wherein were made rich all that had ships in the sea by reason of her
costliness! for in one hour is she made desolate. 18:20 Rejoice over her,
[thou]
heaven, and [ye] holy apostles and prophets; for God hath avenged you on
her.

So we have further evidence that the Saints in heaven are aware of what is
going
on in earth, and they specifically pray for things that go on in earth. We
must
remember that Saints in heaven are not bound by time and space as we are. In
eternity, 1 John 3:2 tells us:

Beloved, we are God's children now; it does not yet appear what we shall be,
but
we know that when he appears we shall be like him, for we shall see him as
he
is.

There is only one body, the Church. The church is not one church in heaven
as
opposed to one church on earth. The one church is intimately connected with
each
other (remember the image of the vine and the branches in John 15). And
those in
heaven are just men made perfect. As the body is called to love each other,
are
the saints in heaven, even though they are aware of what is going on in
earth,
according to scripture just given, careless as to what is going on in the
lives
of those on earth? Of course not!!! Christ calls perfected people to love
the
rest of the body. I can be confident that they will intercede for those on
earth. What does it profit? James explains:

James 5:16 "The effectual fervent prayer of a righteous man availeth much."
Those in heaven are perfectly righteous, and their prayers are efficacious.
How
can one ignore them?

Why can't I just say, I don't need those Saints in heaven to pray for us, I
can
go directly to God. (BTW, Catholics also do pray directly to God.) Why can't
I
say I really don't need the rest of the Church? What does Paul say?

1 Cor. 12:14 For the body is not one member, but many. 12:15 If the foot
shall
say, Because I am not the hand, I am not of the body; is it therefore not of
the
body? 12:16 And if the ear shall say, Because I am not the eye, I am not of
the
body; is it therefore not of the body? 12:17 If the whole body [were] an
eye,
where [were] the hearing? If the whole [were] hearing, where [were] the
smelling? 12:18 But now hath God set the members every one of them in the
body,
as it hath pleased him. 12:19 And if they were all one member, where [were]
the
body? 12:20 But now [are they] many members, yet but one body. 12:21 And the
eye
cannot say unto the hand, I have no need of thee: nor again the head to the
feet, I have no need of you.

As an eye, I cannot say to the hand, I do not need you. However, those who
are
against praying to the saints, do exactly that by neglecting the rest of the
body of Christ.
