He will come when He comes, without losing even one who belongs to Him and who can come to Him. Not all who belong to Him have yet come to Him.
Ummm!! thinking ... thinking.. Oh! yes... Jesus promised:
20 “When you see Jerusalem being surrounded by armies, you will know that its desolation is near. 21 Then let those who are in Judea flee to the mountains, let those in the city get out, and let those in the country not enter the city. 22 For this is the time of punishment in fulfillment of all that has been written. 23 How dreadful it will be in those days for pregnant women and nursing mothers! There will be great distress in the land and wrath against this people. 24 They will fall by the sword and will be taken as prisoners to all the nations. Jerusalem will be trampled on by the Gentiles until the times of the Gentiles are fulfilled.
25 “There will be signs in the sun, moon and stars. On the earth, nations will be in anguish and perplexity at the roaring and tossing of the sea. 26 People will faint from terror, apprehensive of what is coming on the world, for the heavenly bodies will be shaken. 27 At that time they will see the Son of Mancoming in a cloud with power and great glory. 28 When these things begin to take place, stand up and lift up your heads, because your redemption is drawing near.”
29 He told them this parable: “Look at the fig tree and all the trees. 30 When they sprout leaves, you can see for yourselves and know that summer is near. 31 Even so, when you see these things happening, you know that the kingdom of God is near."
32 “Truly I tell you, this generation will certainly not pass away until all these things have happened.
When was Jerusalem surrounded by armies? Was it 66 CE? Yes, that was the year.
haha! Jesus idea of a generation is even longer than the JW generation....
