Modern Bibles weaken God's Promise to Preserve His Word

Most of today's Bible scholars believe in an ideology known as Alexandrinanism.  They believe that God's word was only pure in the originals, but that errors have crept into the Scripture text over the centuries.  Their beilief that only the originals were inerrant sent the scholars looking for the oldest manuscripts because they supposidly were closer to the originals and would have the fewest mistakes.  Thus THEY DO NOT BELIEVE THAT GOD PRESERVED HIS WORD UNTO ALL GENERATIONS LIKE HE PROMISED HE WOULD DO.    Many of the modern versions reflect this belief by weaking God's promise to preserve his Word.

Psalm 12:6,7.

6 The words of the LORD are pure words: as silver tried in a furnace of earth, purified seven times.
7 Thou shalt keep them, O LORD, thou shalt preserve them from this generation for ever.

6 The words of the LORD are pure words; As silver tried in a furnace on the earth, refined seven times.
7You, O LORD, will keep them; You will preserve him from this generation forever.

6 And the words of the Lord are flawless, like silver refined in a furnace of clay, purified seven times.
7 O Lord , you will keep us safe and protect us from such people forever.

(Dr. Gipp notes that the words "us" as used in the NIV have NO basis in ANY Greek manuscript!  See page 324 of "The Understandable History of the Bible" by Sam Gipp)

Psalm 117

1 O praise the LORD, all ye nations: praise him, all ye people.
2 For his merciful kindness is great toward us: and the truth of the LORD endureth for ever.  Praise ye the LORD.

1 Praise the Lord, all you nations; extol him, all you peoples.  
2 For great is his love toward us, and the faithfulness of the Lord endures forever. Praise the Lord .

Psalm 100:5

For the LORD is good; his mercy is everlasting; and his truth endureth to all generations.

For the LORD is good; His lovingkindness is everlasting and His faithfulness to all generations.

For the Lord is good and his love endures forever; his faithfulness continues through all generations.
