Mark 13:26-27: "At that time people will see the Son of Man coming in clouds with great power and glory. And he will send his angels and gather his elect from the four winds, from the ends of the earth to the ends of the heavens. Now learn this lesson from the fig tree: As soon as its twigs get tender and its leaves come out, you know that summer is near. Even so, when you see these things happening, you know that it is near, right at the door.Truly I tell you, this generation will certainly not pass away until all these things have happened. Heaven and earth will pass away, but my words will never pass away. But about that day or hour no one knows, not even the angels in heaven, nor the Son, but only the Father. Be on guard! Be alert! You do not know when that time will come. It’s like a man going away: He leaves his house and puts his servants in charge, each with their assigned task, and tells the one at the door to keep watch. Therefore keep watch because you do not know when the owner of the house will come back—whether in the evening, or at midnight, or when the rooster crows, or at dawn. If he comes suddenly, do not let him find you sleeping. What I say to you, I say to everyone: ‘Watch!’ "
Matthew 24:30-51: "Then will appear the sign of the Son of Man in heaven. And then all the peoples of the earth will mourn when they see the Son of Man coming on the clouds of heaven, with power and great glory. And he will send his angels with a loud trumpet call, and they will gather his elect from the four winds, from one end of the heavens to the other. Now learn this lesson from the fig tree: As soon as its twigs get tender and its leaves come out, you know that summer is near. Even so, when you see all these things, you know that it is near, right at the door. Truly I tell you, this generation will certainly not pass away until all these things have happened. Heaven and earth will pass away, but my words will never pass away. But about that day or hour no one knows, not even the angels in heaven, nor the Son, but only the Father. As it was in the days of Noah, so it will be at the coming of the Son of Man. For in the days before the flood, people were eating and drinking, marrying and giving in marriage, up to the day Noah entered the ark; and they knew nothing about what would happen until the flood came and took them all away. That is how it will be at the coming of the Son of Man. Two men will be in the field; one will be taken and the other left. Two women will be grinding with a hand mill; one will be taken and the other left.Therefore keep watch, because you do not know on what day your Lord will come. But understand this: If the owner of the house had known at what time of night the thief was coming, he would have kept watch and would not have let his house be broken into. So you also must be ready, because the Son of Man will come at an hour when you do not expect him. Who then is the faithful and wise servant, whom the master has put in charge of the servants in his household to give them their food at the proper time?It will be good for that servant whose master finds him doing so WHEN HE RETURNS. Truly I tell you, he will put him in charge of all his possessions. But suppose that servant is wicked and says to himself, ‘My master is staying away a long time,’ and he then begins to beat his fellow servants and to eat and drink with drunkards. The master of that servant WILL COME on a day when he does not expect him and at an hour he is not aware of. He will cut him to pieces and assign him a place with the hypocrites, where there will be weeping and gnashing of teeth.
Matthew 25:14-30: "For it is just like a man about to go on a journey, who called his own slaves and entrusted his possessions to them. To one he gave five talents, to another, two, and to another, one, each according to his own ability; and he went on his journey. Immediately the one who had received the five talents went and traded with them, and gained five more talents. In the same manner the one who had received the two talents gained two more. But he who received the one talent went away, and dug a hole in the ground and hid his master’s money. Now after a long time the MASTER OF THOSE SERVANTS CAME and settled accounts with them.The one who had received the five talents came up and brought five more talents, saying, ‘Master, you entrusted five talents to me. See, I have gained five more talents.’His master said to him, ‘Well done, good and faithful slave. You were faithful with a few things, I will put you in charge of many things; enter into the joy of your master.’Also the one who had received the two talents came up and said, ‘Master, you entrusted two talents to me. See, I have gained two more talents.’ His master said to him, ‘Well done, good and faithful slave. You were faithful with a few things, I will put you in charge of many things; enter into the joy of your master.’ And the one also who had received the one talent came up and said, ‘Master, I knew you to be a hard man, reaping where you did not sow and gathering where you scattered no seed. And I was afraid, and went away and hid your talent in the ground. See, you have what is yours.’ But his master answered and said to him, ‘You wicked, lazy slave, you knew that I reap where I did not sow and gather where I scattered no seed. Then you ought to have put my money in the bank, and on my arrival I would have received my money back with interest. Therefore take away the talent from him, and give it to the one who has the ten talents.’ For to everyone who has, more shall be given, and he will have an abundance; but from the one who does not have, even what he does have shall be taken away. Throw out the worthless slave into the outer darkness; in that place there will be weeping and gnashing of teeth".
Notice also the Parable of the Talents: The Master goes away, and the slaves are judged as either faithful or wicked when the Master returns based on their conduct when he was away. Similarly the faithful and wise servant would not be declared as such until the Master returns (which the Society now interprets as the Great Tribulation). The Society might try to claim that because the going-away is not explicit in the other parable, it may be safely ignored. But the fact is, it is implicit. The Master is described as returning to the house to make an accounting of the servants, he is thus absent when the slave is dispensing food, or when the wicked slave is eating and drinking and mistreating the household (the same theme as "when the cat is away the mice shall play"). The Master however had to have been present in the household when the slaves were given those responsibilities. So although not explicit, there is an implicit departure of the Master that is explicit in the other two parables.
