Again, you should discern with Him the different roles to those two titles since the appearing of the Bridegroom to receive the ready abiding bride to the wedding reception above before the great tribulation is entirely different than when He comes as the King of kings to do battle against the world's armies marching unto Jerusalem to establish His reign on earth at the end of the great tribulation.Therefore, many are called, but few are chosen. Sanctification is a lifetime process,receiving of the gospel is just the start. This is like the relationship of love with your other half, you know, in all kinds of romance fairytales the hero falls in love, beats the villain, saves the girl and kisses the bride and they live happily ever after - for granted, but obviously that's just a fantasy. By God's design, marriage is the sacred union for a lifetime, and the wedding day is the START, not the END as it is portrayed in the movies.
There is a sit down in that kingdom of God which is at the Marriage Supper table above in Heaven with O.T. saints for why saved believers are to be ready or else be excommunicated from above as cast into the bed of the great tribulation.
Luke 13:24 Strive to enter in at the strait gate: for many, I say unto you, will seek to enter in, and shall not be able.
25 When once the master of the house is risen up, and hath shut to the door, and ye begin to stand without, and to knock at the door, saying, Lord, Lord, open unto us; and he shall answer and say unto you, I know you not whence ye are:
26 Then shall ye begin to say, We have eaten and drunk in thy presence, and thou hast taught in our streets.
27 But he shall say, I tell you, I know you not whence ye are; depart from me, all ye workers of iniquity.
28 There shall be weeping and gnashing of teeth, when ye shall see Abraham, and Isaac, and Jacob, and all the prophets, in the kingdom of God, and you yourselves thrust out.
29 And they shall come from the east, and from the west, and from the north, and from the south, and shall sit down in the kingdom of God.
30 And, behold, there are last which shall be first, and there are first which shall be last.
Compare verses 25 & 28-29 above with verses 10-12 below.
Matthew 25:1Then shall the kingdom of heaven be likened unto ten virgins, which took their lamps, and went forth to meet the bridegroom.
2 And five of them were wise, and five were foolish.
3 They that were foolish took their lamps, and took no oil with them:
4 But the wise took oil in their vessels with their lamps.
5 While the bridegroom tarried, they all slumbered and slept.
6 And at midnight there was a cry made, Behold, the bridegroom cometh; go ye out to meet him.
7 Then all those virgins arose, and trimmed their lamps.
8 And the foolish said unto the wise, Give us of your oil; for our lamps are gone out.
9 But the wise answered, saying, Not so; lest there be not enough for us and you: but go ye rather to them that sell, and buy for yourselves.
10 And while they went to buy, the bridegroom came; and they that were ready went in with him to the marriage: and the door was shut.
11 Afterward came also the other virgins, saying, Lord, Lord, open to us.
12 But he answered and said, Verily I say unto you, I know you not.
13 Watch therefore, for ye know neither the day nor the hour wherein the Son of man cometh.
This event of the Bridegroom and leaving those not ready behind can hardly be the same as His coming back as the King of kings with the saints when there is no leaving them behind then when He is coming to earth.
