There is a rabbit hole around authority of scripture, and how this should be interpreted. I will summarise. If you consider scripture as a human activity about God, then the words have no relevance beyond that time. If you consider that they are the word sent by God, that is profitable at all times, and has authority from him, then you better pay attention. The understanding of religion as a human activity, correctly, is a subset of natural theology, and has no power to save.
That comes from Christ. Which is is why we can take the words and promises of Christ, and build our lives upon it.
To do that you need to spend time in the word. For the word of God is powerful, and divides our soul at the joints. If we find that our lives do not adhere to scripture, it is us who needs to reform. This happens too often.
And this world wants us to stop struggling, be complacent, and be shocked when things change suddenly and irrevocably. This world wants us to think the game is the same as it was for our grandfathers and their grandfathers when the goal posts are redefined continually.
This world lies. The reason that they deny the existence of God is that they never want to be accountable for the evil, or the good they have done. They want to live lives of meaningless irrelevance. They want to be Non Playing Characters.
Praise God. For he has not made a world like that, and he has rescued us from that fate.
Heavenly Father, whose blessed Son was revealed to destroy the works of the devil
and to make us the children of God and heirs of eternal life:
Grant that we, having this hope,
may purify ourselves even as he is pure;
that when he shall appear in power and great glory,
we may be made like him
in his eternal and glorious kingdom;
where he is alive and reigns with you and the Holy Spirit, one God, now and for ever.
12 At that time I will search Jerusalem with lamps,
and I will punish the men
who are complacent,
those who say in their hearts,
‘The Lord will not do good,
nor will he do ill.’
13 Their goods shall be plundered,
and their houses laid waste.
Though they build houses,
they shall not inhabit them;
though they plant vineyards,
they shall not drink wine from them.”
14 The great day of the Lord is near,
near and hastening fast;
the sound of the day of the Lord is bitter;
the mighty man cries aloud there.
15 A day of wrath is that day,
a day of distress and anguish,
a day of ruin and devastation,
a day of darkness and gloom,
a day of clouds and thick darkness,
16 a day of trumpet blast and battle cry
against the fortified cities
and against the lofty battlements.
17 I will bring distress on mankind,
so that they shall walk like the blind,
because they have sinned against the Lord;
their blood shall be poured out like dust,
and their flesh like dung.
18 Neither their silver nor their gold
shall be able to deliver them
on the day of the wrath of the Lord.
In the fire of his jealousy,
all the earth shall be consumed;
for a full and sudden end
he will make of all the inhabitants of the earth.
A Prayer of Moses, the man of God.
90 Lord, you have been our dwelling place
in all generations.
2 Before the mountains were brought forth,
or ever you had formed the earth and the world,
from everlasting to everlasting you are God.
3 You return man to dust
and say, “Return, O children of man!”
4 For a thousand years in your sight
are but as yesterday when it is past,
or as a watch in the night.
5 You sweep them away as with a flood; they are like a dream,
like grass that is renewed in the morning:
6 in the morning it flourishes and is renewed;
in the evening it fades and withers.
7 For we are brought to an end by your anger;
by your wrath we are dismayed.
8 You have set our iniquities before you,
our secret sins in the light of your presence.
5 Now concerning the times and the seasons, brothers, you have no need to have anything written to you. 2 For you yourselves are fully aware that the day of the Lord will come like a thief in the night. 3 While people are saying, “There is peace and security”, then sudden destruction will come upon them as labour pains come upon a pregnant woman, and they will not escape. 4 But you are not in darkness, brothers, for that day to surprise you like a thief. 5 For you are all children of light, children of the day. We are not of the night or of the darkness. 6 So then let us not sleep, as others do, but let us keep awake and be sober. 7 For those who sleep, sleep at night, and those who get drunk, are drunk at night. 8 But since we belong to the day, let us be sober, having put on the breastplate of faith and love, and for a helmet the hope of salvation. 9 For God has not destined us for wrath, but to obtain salvation through our Lord Jesus Christ, 10 who died for us so that whether we are awake or asleep we might live with him. 11 Therefore encourage one another and build one another up, just as you are doing.
