I have already pointed out that the denial and rejection of the Resurrection/Rapture and the visible return of Christ are heresies.
Without the actual Resurrection/Rapture, God's plan redemption for the Church is incomplete. Without the actual Second Coming of Christ, God's plan of redemption for the earth is incomplete. So if you do not think this is heretical, perhaps your should examine your own beliefs.
I agree the Second Coming of Jesus is a vital part of any eschatology.
But you lose me at this so-called "rapture" which is not in the Bible (I am quite willing to look at harpazo in 1 Thess 4:17, and show why it does not mean rapture). But even if it were there, one mention of something so important you are willing to call me a heretic, but is not found elsewhere in the Bible is not enough scripture to invent a doctrine.. And people being "taken" is poor application of hermeneutical principles.
So, you have an extremely "iffy" proposition called a Rapture, unsupported in the Bible, and you call me a heretic? For reading what is in the Bible, rather than believe in something that is not there, but, a lot of people think it is!
The real lie is dispensationalism. It has also captured so many people in this snare, where end times becomes all consuming, and even dispensationalist raging with one another about the interpretation of Rev., and the timing of Christ's return, complicated by a false doctrine which keeps people from keeping there eyes focused of God, rather than events!
"keeping our eyes fixed on Jesus, the pioneer and perfecter of our faith. For the joy set out for him he endured the cross, disregarding its shame, and
has taken his seat at the right hand of the throne of God." Hebrews 12:2
Now that's a real "end times" verse.
Finally, God wants us to be transformed into the image of Christ. There are many places this is commanded, both how to do it, and the results like the fruits of the Spirit.
"Do not be conformed to this present world, but be transformed by the renewing of your mind, so that you may test and approve what is the will of God—what is good and well-pleasing and perfect." Romans 12:2
Jesus does not want us navel gazing and doing nothing! He wants us to be involved with business as the excerpt from this parable says:
"And he called his ten servants, and delivered them ten pounds, and said unto them, Occupy till I come." Hebrews 19:13
It always amazes me the obsession with eschatology. Instead, we need to be changing and following a Christ.
"We all, with unveiled faces, are looking as in a mirror at the glory of the Lord and are being transformed into the same image from glory to glory; this is from the Lord who is the Spirit" 1 Cor 3:18
