Here are a few examples why Catholics know and believe that the Saints in heaven are forever praying for us, because Catholics believe God is a God of the living not the dead;
The biblical Catholic doctrine of the Communion of Saints is living proof that she was built by Jesus Christ, and that her Apostolic Belief’s begin on earth in the body of Jesus which is the Catholic Church militant united with the triumphant Catholic Church in heaven. For Catholics do not believe in a god of the dead but the One True God of the Living;
Mark 12:24 Jesus said to them, **“Are you not misled because you do not know the scriptures or the power of God? **25 When they rise from the dead, they neither marry nor are given in marriage, but they are like the angels in heaven.
26 As for the dead being raised, ]have you not read in the Book of Moses, in the passage about the bush, how God told him, ‘I am the God of Abraham, (the) God of Isaac, and (the) God of Jacob’?
27 He is not God of the dead but of the living. You are greatly misled.”
Luke 20:34 Jesus said to them, “The children of this age marry and remarry;
35 but those who are deemed worthy to attain to the coming age and to the resurrection of the dead neither marry nor are given in marriage.
36 **They can no longer die, for they are like angels; and they are the children of God because they are the ones who will rise. 9 **37 That the dead will rise even Moses made known in the passage about the bush, when he called **‘Lord’ the God of Abraham, the God of Isaac, and the God of Jacob;
38 and he is not God of the dead, but of the living, for to him all are alive.” /**U]
Not even death can separate us from God, this follows in the biblical teaching of the communion of Saints;
Romans 8:35 What will separate us from the love of Christ? Will anguish, or distress, or persecution, or famine, or nakedness, or peril, or the sword?
36 As it is written: “For your sake we are being slain all the day; we are looked upon as sheep to be slaughtered.”
37 No, in all these things we conquer overwhelmingly through him who loved us.
38 For I am convinced that neither death, nor life, nor angels, nor principalities, nor present things, 9 nor future things, nor powers,
39 nor height, nor depth, 10 nor any other creature will be able to separate us from the love of God in Christ Jesus our Lord.
Hear is Jesus conversing with Moses and Elijah by eyewitnesses long after God had taken them. Just as all Saints and Martyrs are before the presence of God; God is the same yesterday, today and forever.
Mark 9:2 After six days Jesus took Peter, James, and John and led them up a high mountain apart by themselves. And he was transfigured before them,
3 and his clothes became dazzling white, such as no fuller on earth could bleach them.
4 Then Elijah appeared to them along with Moses, and they were conversing with Jesus.
Here Jesus promises the good thief, that “today” he will be with him in paradise;
Luke 23:39-Now one of the criminals hanging there reviled Jesus, saying, “Are you not the Messiah? Save yourself and us.”
40 The other, however, rebuking him, said in reply, “Have you no fear of God, for you are subject to the same condemnation?
41 And indeed, we have been condemned justly, for the sentence we received corresponds to our crimes, but this man has done nothing criminal.”
42 Then he said, “Jesus, remember me when you come into your kingdom.”
43 He replied to him, “Amen, I say to you, today you will be with me in Paradise.”
Revelations 14:1 Then I looked and there was the Lamb standing on Mount Zion, 2 and with him a hundred and forty-four thousand who had his name and his Father’s name written on their foreheads.
4… They have been ransomed as the firstfruits of the human race for God and the Lamb.
Revelations 14:13 I heard a voice from heaven say, ]“Write this: Blessed are the dead who die in the Lord from now on.” “Yes,” said the Spirit, “let them find rest from their labors, for their works accompany them.”
Revelations 21:33 I heard a loud voice from the throne saying, **“Behold, God’s dwelling is with the human race. He will dwell with them and they will be his people and God himself will always be with them (as their God).
4 He will wipe every tear from their eyes, and there shall be no more death or mourning, wailing or pain, (for) the old order has passed away.”
5 The one who sat on the throne 5 said, “Behold, I make all things new.” Then he said, “Write these words down, for they are trustworthy and true.” **6 He said to me, "They are accomplished. 6 I (am) the Alpha and the Omega, the beginning and the end. To the thirsty I will give a gift from the spring of life-giving water.
7 The victor will inherit these gifts, and I shall be his God, and he will be my son.
