Another thing people miss is when He came in what we call His First Coming, is that He actually came twice. One time to a great announcement to the people, such as His star and angels singing. The other time was after the resurrection after He forbade Martha from touching Him because He had not yet gone onto the Father, but then a short time later He told others to touch Him. That's an indicator that He left and came back again, but this time it was silent, with no announcement or fanfare. The Second Coming has the same type of appearance. The first will be silent, with no fanfare, the second will see the stars roll away, trumpets will blast, and all eyes will see Him.
Another thing people miss is the example He gives us in the three-stage harvest. We have the firstfruits, the main harvest, and then the gleanings. In the first two stages, God declares the grain gathered belongs to the owner of the field, but the last, the gleanings or the edges of the field, belong to the poor and outcast.
We've already seen the offering of the firstfruits. Paul describes this as the resurrection of Christ in 1 Corinthians 15:23. That verse also describes the main harvest at His next coming, where those who belong to God are taken (raptured). That's the first two stages where God, the owner of the field, gathers what belongs to Him.
Then in verses 24 and 25, Paul does this funny little thing and states concerning stage 3, the gleanings, that's the part which he states occurs at the end, at the time Jesus comes to end the rulers of this earth and begin to reign. So, when you are reading passages concerning the time when He comes in great power and setting up His Kingdom, you are reading about the 3rd stage of the harvest. The first two stages had already past.
