I could give you all sorts of 'rebuttals,' which surely would be engraved in my own understanding, thoughts, and introspect,
but I know what the Word says, and i will stick to what the Word says.
1 Peter 1:23
Being born again, not of corruptible seed, but of incorruptible, by the word of God, which liveth and abideth for ever.
As I can see it, the rapture doctrine is a stumbling block and a cause for stumbling, leading people into all sorts of fantasy that stray from what we know to be true. When you're born again, you are sealed by the Holy Spirit, and He indwells you, and works to bring forth fruit for the Kingdom of God through us, and through the Holy Spirit, Jesus reigns in us and through us.
As for the rapture, there is not one thing I can see from any of the speculative, 'speculative,' doctrine which edifies the Church in any way, but the opposite I see; it is a stumbling block, a cause for concern, stealing believers away from the Word.
Matthew 6:25-34
25 Therefore I say unto you, Take no thought for your life, what ye shall eat, or what ye shall drink; nor yet for your body, what ye shall put on. Is not the life more than meat, and the body than raiment?
26 Behold the fowls of the air: for they sow not, neither do they reap, nor gather into barns; yet your heavenly Father feedeth them. Are ye not much better than they?
27 Which of you by taking thought can add one cubit unto his stature?
28 And why take ye thought for raiment? Consider the lilies of the field, how they grow; they toil not, neither do they spin:
29 And yet I say unto you, That even Solomon in all his glory was not arrayed like one of these.
30 Wherefore, if God so clothe the grass of the field, which to day is, and to morrow is cast into the oven, shall he not much more clothe you, O ye of little faith?
31 Therefore take no thought, saying, What shall we eat? or, What shall we drink? or, Wherewithal shall we be clothed?
32 (For after all these things do the Gentiles seek
for your heavenly Father knoweth that ye have need of all these things.
33 But seek ye first the kingdom of God, and his righteousness; and all these things shall be added unto you.
34 Take therefore no thought for the morrow: for the morrow shall take thought for the things of itself. Sufficient unto the day is the evil thereof.
It is clear to me that the rapture
'speculation' goes against this scripture, and outright; once more, it is a stumbling block, a worrisome thing, a cause for needless concern; there is nothing at all for us to gain through it, and it is a waste of precious time, and a thief.
