Second coming of Christ

Mark 13:24 But in those days, after that tribulation, the sun shall be darkened, and the moon shall not give her light, 25 And the stars of heaven shall fall, and the powers that are in heaven shall be shaken. Matt 24:29 Immediately after the tribulation of those days shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken: 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; 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.
Mark 13:26 And then shall they see the Son of man coming in the clouds with great power and glory. Matt 24:30 And then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory. Luke 21:27 And then shall they see the Son of man coming in a cloud with power and great glory.
Mark 13:27 And then shall he send his angels, and shall gather together his elect from the four winds, from the uttermost part of the earth to the uttermost part of heaven. Matt 24:31 And he shall send his angels with a great sound of a trumpet, and they shall gather together his elect from the four winds, from one end of heaven to the other.
       

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.
