Ps 37:39
But the salvation of the righteous is from the LORD; He is their strength in time of trouble.
kingsvine implies (with "either/or" reasoning and the bolded word) that
only God can be a strength, and that this somehow precludes human beings participating in the strengthening other human beings in time of need. The Bible doesn't teach that. So, for example, we see the following:
Deuteronomy 3:28 But charge Joshua, and encourage and
strengthen him; for he shall go over at the head of this people, and he shall put them in possession of the land which you shall see.' [God speaking to Moses]
1 Samuel 23:16 And Jonathan, Saul's son, rose, and went to David at Horesh, and
strengthened his hand in God. (cf. 2 Chron 11:16-17)
Ecclesiastes 7:19 Wisdom gives
strength to the wise man more than ten rulers that are in a city.
Daniel 11:1 And as for me [Daniel], in the first year of Darius the Mede, I stood up to confirm and
strengthen him.
Luke 22:32 but I have prayed for you [Peter] that your faith may not fail; and when you have turned again,
strengthen your brethren.
Acts 14:22 [Paul and Barnabas]
strengthening the souls of the disciples, exhorting them to continue in the faith, and saying that through many tribulations we must enter the kingdom of God.
Acts 15:32 And Judas and Silas, who were themselves prophets, exhorted the brethren with many words and
strengthened them.
Acts 15:41 And he [Paul] went through Syria and Cili'cia,
strengthening the churches.
Acts 16:4-5 As they [Paul and Timothy] went on their way through the cities, they delivered to them for observance the decisions which had been reached by the apostles and elders who were at Jerusalem. [5] So the churches were
strengthened in the faith, and they increased in numbers daily.
Acts 18:23 After spending some time there he [Paul] departed and went from place to place through the region of Galatia and Phryg'ia,
strengthening all the disciples.
Romans 1:11 For I [Paul] long to see you,
that I may impart to you some spiritual gift to
strengthen you,
[St. Paul in turn gives God the ultimate credit as the original source of all such strength, channeled through himself and other spiritual leaders ("both/and" reasoning again): Rom 16:15; Eph 3:16; 6:10; Phil 4:13; Col 1:11; 2 Thess 3:3; 1 Tim 1:12; 2 Tim 2:1; 4:17. So does St. Peter: 1 Pet 4:11; 5:10]
At least one passage even illustrates how God uses things in His creation to strengthen man:
Psalm 104:13-15 From thy lofty abode thou waterest the mountains;
the earth is satisfied with the fruit of thy work.
[14] Thou dost cause the grass to grow for the cattle,
and plants for man to cultivate,
that he may bring forth food from the earth,
[15] and wine to gladden the heart of man,
oil to make his face shine,
and bread to
strengthen man's heart.
Note how "heart" is used instead of body. This refers to the spirit, not merely physical energy from nutrition.
Encouragement (Deut 1:38; 2 Chron 35:2; Acts 18:27; 20:2; 27:36; Rom 1:12; 1 Cor 14:3, 31; Eph 6:22; Col 2:2; 4:8; 1 Thess 2:11;5:11, 14) and
exhortation (Lk 3:18; Acts 2:40; 11:23; 14:22; 15:31-32; 16:40; 20:1; Rom 12:8; 1 Thess 2:11; 3:2; 4:1, 10; 5:14; 2 Thess 3:12; 1 Tim 5:1; 2 Tim 4:2; Titus 2:15; Heb 3:13; 13:22; 1 Pet 5:1, 12) and
help (Gen 2:18, 20; Is 41:6 [cf. 10, 13-14]; Acts 16:9; 18:27; 20:35; Rom 16:2; 1 Cor 12:28; 2 Cor 1:11; 1 Thess 5:14) from
others (not solely God to the exclusion of men) are similar biblical concepts.
Comfort (of the spiritual sort) is also referred to as coming from fellow human beings: not just from God:
1 Chronicles 7:22 And E'phraim their father mourned many days, and his brothers came to comfort him.
Job 42:11 Then came to him all his brothers and sisters and all who had known him before, and ate bread with him in his house; and they showed him sympathy and comforted him for all the evil that the LORD had brought upon him; and each of them gave him a piece of money and a ring of gold.
2 Corinthians 1:4, 6-7 who comforts us in all our affliction, so that we may be able to comfort those who are in any affliction, with the comfort with which we ourselves are comforted by God. . . . [6] If we are afflicted, it is for your comfort and salvation; and if we are comforted, it is for your comfort, which you experience when you patiently endure the same sufferings that we suffer. [7] Our hope for you is unshaken; for we know that as you share in our sufferings, you will also share in our comfort.
2 Corinthians 2:7 so you should rather turn to forgive and comfort him, or he may be overwhelmed by excessive sorrow.
2 Corinthians 7:7 and not only by his coming but also by the comfort with which he was comforted in you, as he told us of your longing, your mourning, your zeal for me, so that I rejoiced still more. (cf. 7:4, 6, 13)
Colossians 4:11 and Jesus who is called Justus. These are the only men of the circumcision among my fellow workers for the kingdom of God, and they have been a comfort to me.
1 Thessalonians 3:7 for this reason, brethren, in all our distress and affliction we have been comforted about you through your faith;
1 Thessalonians 4:18 Therefore comfort one another with these words.
Philemon 1:7 For I have derived much joy and comfort from your love, my brother, because the hearts of the saints have been refreshed through you.
God even compares His comfort with human (and animal) maternal comfort and care:
Isaiah 66:13 As one whom his mother comforts, so I will comfort you; you shall be comforted in Jerusalem.
Matthew 23:37 O Jerusalem, Jerusalem, killing the prophets and stoning those who are sent to you! How often would I have gathered your children together as a hen gathers her brood under her wings, and you would not!
Lastly, human beings extend to each other God's peace -- as well as grace (God is not the only One who does this, though He is the ultimate origin and cause of it):
Judges 18:6 And the priest said to them, "Go in peace. The journey on which you go is under the eye of the LORD."
1 Samuel 1:17 Then Eli answered, "Go in peace, and the God of Israel grant your petition which you have made to him."
1 Samuel 25:6 And thus you shall salute him: `Peace be to you, and peace be to your house, and peace be to all that you have. (cf. 25:35)
Matthew 5:9 Blessed are the peacemakers, for they shall be called sons of God.
Matthew 10:13 And if the house is worthy, let your peace come upon it; but if it is not worthy, let your peace return to you.
Luke 10:5-6 Whatever house you enter, first say, `Peace be to this house!' [6] And if a son of peace is there, your peace shall rest upon him; but if not, it shall return to you.
Acts 16:36 And the jailer reported the words to Paul, saying, "The magistrates have sent to let you go; now therefore come out and go in peace."

Revelation 1:4 John to the seven churches that are in Asia: Grace to you and peace from him who is and who was and who is to come, and from the seven spirits who are before his throne,
Now, Mary and other saints are still alive; they are not unconscious or nonexistent. Much in the Bible indicates a consciousness of earthly affairs from heaven (especially in Revelation: see, e.g., Rev 6:9-10; cf. Heb 12:1). So, for example, Jesus rebuked the Sadducees, who denied the resurrection and afterlife:
Matthew 22:29-32 But Jesus answered them, "You are wrong, because you know neither the scriptures nor the power of God.
[30] For in the resurrection they neither marry nor are given in marriage, but are like angels in heaven.
[31] And as for the resurrection of the dead, have you not read what was said to you by God,
[32] `I am the God of Abraham, and the God of Isaac, and the God of Jacob'? He is not God of the dead, but of the living."
Mark 12:26-27 And as for the dead being raised, have you not read in the book of Moses, in the passage about the bush, how God said to him, `I am the God of Abraham, and the God of Isaac, and the God of Jacob'? [27] He is not God of the dead, but of the living; you are quite wrong."
Luke 20:34-38 And Jesus said to them, "The sons of this age marry and are given in marriage; [35] but those who are accounted worthy to attain to that age and to the resurrection from the dead neither marry nor are given in marriage, [36] for they cannot die any more, because they are equal to angels and are sons of God, being sons of the resurrection. [37] But that the dead are raised, even Moses showed, in the passage about the bush, where he calls the Lord the God of Abraham and the God of Isaac and the God of Jacob.
[38] Now he is not God of the dead, but of the living; for all live to him."
If one denies this, then they have other serious problems with biblical revelation. Therefore, Mary and other departed saints can extend to us these blessings and graces, such as peace, comfort, encouragement, help, exhortation, and strength, just as believers extend these things to each other on earth. Death does not end participation in the Body of Christ. To the contrary, it magnifies it and makes it more powerful. And Mary, as the Mother of God the Son, has more power than any other creature to pray and comfort those of us on earth who ask for her aid.
