I call this painting "THE COMING". One day Jesus will come on the clouds like a thief in the night and take us who are alive in Christ and leave the unbelievers behind for the great tribulation.
Matthew 24:30-31 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. 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.
1 Thessalonians 4: 16-18 For the Lord himself shall descend from heaven with a shout, with the voice of an archangel, and with the trump of God: and the dead in Christ shall rise first: 17 Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord. 18 Wherefore comfort one another with these words.
Daniel 12: 1-2 And at that time shall Michael stand up, the great prince which standeth for the children of thy people: and there shall be a time of trouble, such as never was since there was a nation even to that same time: and at that time thy people shall be delivered, every one that shall be found written in the book. 2 And many of them that sleep in the dust of the earth shall awake, some to everlasting life, and some to shame and everlasting contempt.
There is a judgement coming to this world and I'd rather be with Jesus in heaven than on the earth going through judgement.
