There are Spiritual signs as well.
Ecclesiastes 3King James Version (KJV)
3 To every thing there is a season, and a time to every purpose under the heaven:
2 A time to be born, and a time to die; a time to plant, and a time to pluck up that which is planted;
3 A time to kill, and a time to heal; a time to break down, and a time to build up;
4 A time to weep, and a time to laugh; a time to mourn, and a time to dance;
5 A time to cast away stones, and a time to gather stones together; a time to embrace, and a time to refrain from embracing;
6 A time to get, and a time to lose; a time to keep, and a time to cast away;
7 A time to rend, and a time to sew; a time to keep silence, and a time to speak;
8 A time to love, and a time to hate; a time of war, and a time of peace.
9 What profit hath he that worketh in that wherein he laboureth?
10 I have seen the travail, which God hath given to the sons of men to be exercised in it.
11 He hath made every thing beautiful in his time: also he hath set the world in their heart, so that no man can find out the work that God maketh from the beginning to the end.
12 I know that there is no good in them, but for a man to rejoice, and to do good in his life.
13 And also that every man should eat and drink, and enjoy the good of all his labour, it is the gift of God.
14 I know that, whatsoever God doeth, it shall be for ever: nothing can be put to it, nor any thing taken from it: and God doeth it, that men should fear before him.
15 That which hath been is now; and that which is to be hath already been; and God requireth that which is past.
16 And moreover I saw under the sun the place of judgment, that wickedness was there; and the place of righteousness, that iniquity was there.
17 I said in mine heart, God shall judge the righteous and the wicked: for there is a time there for every purpose and for every work.
18 I said in mine heart concerning the estate of the sons of men, that God might manifest them, and that they might see that they themselves are beasts.
19 For that which befalleth the sons of men befalleth beasts; even one thing befalleth them: as the one dieth, so dieth the other; yea, they have all one breath; so that a man hath no preeminence above a beast: for all is vanity.
20 All go unto one place; all are of the dust, and all turn to dust again.
21 Who knoweth the spirit of man that goeth upward, and the spirit of the beast that goeth downward to the earth?
22 Wherefore I perceive that there is nothing better, than that a man should rejoice in his own works; for that is his portion: for who shall bring him to see what shall be after him?

Ephesians 5
6 Let no man deceive you with vain words: for because of these things cometh the wrath of God upon the children of disobedience.
7 Be not ye therefore partakers with them.
8 For ye were sometimes darkness, but now are ye light in the Lord: walk as children of light:
9 (For the fruit of the Spirit is in all goodness and righteousness and truth
10 Proving what is acceptable unto the Lord.
11 And have no fellowship with the unfruitful works of darkness, but rather reprove them.
12 For it is a shame even to speak of those things which are done of them in secret.
13 But all things that are reproved are made manifest by the light: for whatsoever doth make manifest is light.
14 Wherefore he saith, Awake thou that sleepest, and arise from the dead, and Christ shall give thee light.
15 See then that ye walk circumspectly, not as fools, but as wise,
16 Redeeming the time, because the days are evil.
17 Wherefore be ye not unwise, but understanding what the will of the Lord is.
18And be not drunk with wine, wherein is excess; but be filled with the Spirit;
…5and on her forehead a name was written, a mystery, "BABYLON THE GREAT, THE MOTHER OF HARLOTS AND OF THE ABOMINATIONS OF THE EARTH." 6And I saw the woman drunk with the blood of the saints, and with the blood of the witnesses of Jesus. When I saw her, I wondered greatly.
This woman is spoken of in Jeremiah.
Done in secret, as in the abomination of desolation spoken of in Daniel.
