Well the original Hebrew and Greek texts still exist and there are some extra-Biblical documents that exist to help prove events really did happen. Also Hebrew and Greek are languages that are still spoken and learnt, so if you ever had the time to, you could study the texts yourself. Look into museums and language experts. You can make the comparisons yourself. You'll find there to be little difference. The only 'changes' there would be is where the Hebrew or Greek have individual words that English cannot 100% translate, but roughly can explain, and vice versa, such as the word 'sky/heaven/place above the earth', and even the word 'love'.
And where are you receiving this 'information' on future events? No where is it prophesied before or after Christ that Satan will change 'the laws in scripture'. This is a false prophecy. If you used to be a Satanist there's a chance there are demons still distracting you from God's word, so you must hold up any 'new' teaching against Scripture to see if it is true. The reality is, the devil does anything to stop you being involved with God's word (which is given to us in the Bible) 'Beloved, do not believe every spirit, but test the spirits to see whether they are from God, for many false prophets have gone out into the world.'(1 John 4:1).
"If a revelation is made to another sitting there, let the first be silent. 31 For you can all prophesy one by one, so that all may learn and all be encouraged, 32 and the spirits of prophets are subject to prophets. 33 For God is not a God of confusion but of peace." (1 Cor 14)
"Prophets are subject to prophets" which means your "revelation" needs to be held subject and compared against original scriptures/prophecies. If they do not align, they are false.
It is true the devil does deceive, but God's word triumphs over the devil's lies. The word of God is a sword, the Bible is our weapon against the demons. This is our reality. His Word is a living thing and can be used to defeat the enemy. It is not the devil's book, it is God's.
"In the beginning was the Word, and the Word was with God, and the Word was God." John 1:1
"For the word of God is living and active, sharper than any two-edged sword, piercing to the division of soul and of spirit, of joints and of marrow, and discerning the thoughts and intentions of the heart."(Hebrews 4:12)
I still find it ironic that you will listen to sermons and Christian websites, yet the very thing they use as number 1 reference and resource IS the Bible, but you won't read/study it. You trust sinful humans over God.
