In the sky

The sky was alive with clouds and streaks. The sky will show signs. Signs of the devil's activity, signs of man's presence and power and end time signs of the coming of the Lord.

Eph_2:2  Wherein in time past ye walked according to the course of this world, according to the prince of the power of the air, the spirit that now worketh in the children of disobedience: 

We were subject to the prince of the power of the air, the devil and sin. God broke this power over us by coming as Jesus, the Son of God to destroy the work of the devil and to redeem us with his shed blood. He gave us a great commission.

Act 1:8  But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth. 

Signs of two angels , a dead tree (the cross) and a cloud.

Act 1:9  And when he had spoken these things, while they beheld, he was taken up; and a cloud received him out of their sight. 

Act 1:10  And while they looked stedfastly toward heaven as he went up, behold, two men stood by them in white apparel; 

Act 1:11  Which also said, Ye men of Galilee, why stand ye gazing up into heaven? this same Jesus, which is taken up from you into heaven, shall so come in like manner as ye have seen him go into heaven. 

Jesus is coming in the clouds. Do you hear the sound of a trumpet?

1Co 15:51  Behold, I shew you a mystery; We shall not all sleep, but we shall all be changed, 
1Co 15:52  In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed. 
1Co 15:53  For this corruptible must put on incorruption, and this mortal must put on immortality. 

Luke 21:25  And there shall be signs in the sun, and in the moon, and in the stars; and upon the earth distress of nations, with perplexity; the sea and the waves roaring; 
Luke 21:26  Men's hearts failing them for fear, and for looking after those things which are coming on the earth: for the powers of heaven shall be shaken. 
Luke 21:27  And then shall they see the Son of man coming in a cloud with power and great glory. 

Luke 21:28  And when these things begin to come to pass, then look up, and lift up your heads; for your redemption draweth nigh. 

The End Times

Some scholars think that the account of the end times in Matthew, referred to the end of the Jewish state and temple after the Lord's first coming.

Mat 24:4  And Jesus answered and said unto them, Take heed that no man deceive you. 
Mat 24:5  For many shall come in my name, saying, I am Christ; and shall deceive many. 
Mat 24:6  And ye shall hear of wars and rumours of wars: see that ye be not troubled: for all these things must come to pass, but the end is not yet. 
Mat 24:7  For nation shall rise against nation, and kingdom against kingdom: and there shall be famines, and pestilences, and earthquakes, in divers places. 
Mat 24:8  All these are the beginning of sorrows. 
Mat 24:9  Then shall they deliver you up to be afflicted, and shall kill you: and ye shall be hated of all nations for my name's sake. 
Mat 24:10  And then shall many be offended, and shall betray one another, and shall hate one another. 
Mat 24:11  And many false prophets shall rise, and shall deceive many. 
Mat 24:12  And because iniquity shall abound, the love of many shall wax cold. 
Mat 24:13  But he that shall endure unto the end, the same shall be saved. 

Mat 24:14 And this gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come.

Mat 24:15  When ye therefore shall see the abomination of desolation, spoken of by Daniel the prophet, stand in the holy place, (whoso readeth, let him understand:) 

and then shall the end come; not the end of the world, as the Ethiopic version reads it, and others understand it; but the end of the Jewish state, the end of the city and temple: so that the universal preaching of the Gospel all over the world, was the last criterion and sign, of the destruction of Jerusalem; and the account of that itself next follows, with the dismal circumstances which attended it. (Gill)

 Often the prophesies have a near and an end time fulfillment. Luke spoke of the end times as well.

Luk 21:20 And when ye shall see Jerusalem compassed with armies, then know that the desolation thereof is nigh.
Luk 21:21 Then let them which are in Judaea flee to the mountains; and let them which are in the midst of it depart out; and let not them that are in the countries enter thereinto.
Luk 21:22 For these be the days of vengeance, that all things which are written may be fulfilled.
Luk 21:23 But woe unto them that are with child, and to them that give suck, in those days! for there shall be great distress in the land, and wrath upon this people.
Luk 21:24 And they shall fall by the edge of the sword, and shall be led away captive into all nations: and Jerusalem shall be trodden down of the Gentiles, until the times of the Gentiles be fulfilled.
Luk 21:25 And there shall be signs in the sun, and in the moon, and in the stars; and upon the earth distress of nations, with perplexity; the sea and the waves roaring;
Luk 21:26 Men's hearts failing them for fear, and for looking after those things which are coming on the earth: for the powers of heaven shall be shaken.
Luk 21:27 And then shall they see the Son of man coming in a cloud with power and great glory.

For me, both accounts are to warn us, to give us signs to look for and to prepare our hearts for his coming. Both accounts point to the coming of our Lord for his people. There will be tribulations, but we will be with Jesus in the end. To the Jewish people in 70 AD, when the Romans destroyed their city and temple, it seemed like the end to them, but the end had not yet come.  We are to be ready for his coming at any time. Some cults teach that Jesus has already returned. We were warned not to believe in false Christs.

Mat 24:5  For many shall come in my name, saying, I am Christ; and shall deceive many. 

The abomination has not come yet, the antichrist, the beast who shall enter the temple and declare himself to be the Christ.

Mat 24:15  When ye therefore shall see the abomination of desolation, spoken of by Daniel the prophet, stand in the holy place, (whoso readeth, let him understand:) 

We are to know the times by the descriptions of the end times and to be ready. We will know the season before the world knows, because we have the Holy Spirit who warns us.
