Preservation of Scripture
Psalm 12:6-7 NKJV
The words of the LORD are pure words, Like silver tried in a furnace of earth, Purified seven times.  You shall keep them, O LORD, You shall preserve them from this generation forever.

Forever, O LORD, Your word is settled in heaven.
Psalm 119:151-152 NKJV
You are near, O LORD, And all Your commandments are truth.  Concerning Your testimonies, I have known of old that You have founded them forever.
Psalm 119:160 NKJV
The entirety of Your word is truth, And every one of Your righteous judgments endures forever.
Matthew 24:35 NKJV
Heaven and earth will pass away, but My words will by no means pass away.
1 Peter 1:22-25 NKJV
Since you have purified your souls in obeying the truth through the Spirit in sincere love of the brethren, love one another fervently with a pure heart,  having been born again, not of corruptible seed but incorruptible, through the word of God which lives and abides forever,  because “All flesh is as grass, And all the glory of man as the flower of the grass. The grass withers, And its flower falls away,  But the word of the LORD endures forever.” Now this is the word which by the gospel was preached to you..
Ecclesiastes 3:11-15 NKJV
He has made everything beautiful in its time. Also He has put eternity in their hearts, except that no one can find out the work that God does from beginning to end.  I know that nothing is better for them than to rejoice, and to do good in their lives,  and also that every man should eat and drink and enjoy the good of all his labor-it is the gift of God.  I know that whatever God does, It shall be forever. Nothing can be added to it, And nothing taken from it. God does it, that men should fear before Him.  That which is has already been, And what is to be has already been; And God requires an account of what is past.
