I've noticed that people often speak as though they are desperate to be raptured, or on the other hand they are supremely confident that they will chosen for the pre-tribulation lifting-up that is soon to occur.

HOWEVER, any person's "desire to be raptured" AND/OR the confidence that one has that they will be raptured has NOTHING TO DO with who God chooses to take during the first harvest, except for this ... those that want to escape to be removed from their troubles (self-preservation, rather than love for the Bridegroom) reveal that they love themselves more than Him and are less likely to be taken ... and those that have confidence in themselves that they will be taken are adopting an attitude of high-mindedness that is NOT typical of the "lowly of the lowly" which lowers their likelihood of being of the elect of His heart as well. 

Many are called, but few will be chosen.  Not everyone that is "heaven bound" is also "rapture ready."

Contrast these common attributes with the rare attitudes that personify matchless humility. 
Isn't it easier to respect His decision if the Lord selects the Bride whose interest in being lifted-up at the first harvest simply having to do with the fulfillment of her heart's desire in His arms, and very little thought is given about escaping misery from the world or other predicaments?  For such a person has demonstrated abandonment of their own self-interests and the ability to be grateful for all things about which others are discontented in this world.
Isn't it also easier to respect His choice if the Lord selects a Bride who isn't so sure and self-confident that she has caught His eye to escape tribulation when innocent children are taken from the world?  Such a bride as this has a lower estimation of their self and has meekness with regard to their place in God's plans.

From Luke 14:7When he noticed how the guests picked the places of honor at the table, he told them this parable: 8“When someone invites you to a wedding feast, do not take the place of honor, for a person more distinguished than you may have been invited. 9If so, the host who invited both of you will come and say to you, ‘Give this man your seat.’ Then, humiliated, you will have to take the least important place. 10But when you are invited, take the lowest place, so that when your host comes, he will say to you, ‘Friend, move up to a better place.’ Then you will be honored in the presence of all your fellow guests. 11For everyone who exalts himself will be humbled, and he who humbles himself will be exalted.”

12Then Jesus said to his host, “When you give a luncheon or dinner, do not invite your friends, your brothers or relatives, or your rich neighbors; if you do, they may invite you back and so you will be repaid. 13But when you give a banquet, invite the poor, the crippled, the lame, the blind, 14and you will be blessed. Although they cannot repay you, you will be repaid at the resurrection of the righteous.”

The Parable of the Great Banquet

15When one of those at the table with him heard this, he said to Jesus, “Blessed is the man who will eat at the feast in the kingdom of God.”

16Jesus replied: “A certain man was preparing a great banquet and invited many guests. 17At the time of the banquet he sent his servant to tell those who had been invited, ‘Come, for everything is now ready.’

18“But they all alike began to make excuses. The first said, ‘I have just bought a field, and I must go and see it. Please excuse me.’

19“Another said, ‘I have just bought five yoke of oxen, and I’m on my way to try them out. Please excuse me.’

20“Still another said, ‘I just got married, so I can’t come.’

21“The servant came back and reported this to his master. Then the owner of the house became angry and ordered his servant, ‘Go out quickly into the streets and alleys of the town and bring in the poor, the crippled, the blind and the lame.’

22“‘Sir,’ the servant said, ‘what you ordered has been done, but there is still room.’

23“Then the master told his servant, ‘Go out to the roads and country lanes and make them come in, so that my house will be full. 24I tell you, not one of those men who were invited will get a taste of my banquet.’”
