Psalms 56:10-11
[10 ] In God will I praise his word: in the LORD will I praise his word.
[11 ] In God have I put my trust: I will not be afraid what man can do unto me.
Joshua 1:8-9
[8] This book of the law shall not depart out of thy mouth; but thou shalt meditate therein day and night, that thou mayest observe to do according to all that is written therein: for then thou shalt make thy way prosperous, and then thou shalt have good success.
[9] Have not I commanded thee? Be strong and of a good courage; be not afraid, neither be thou dismayed: for the LORD thy God is with thee whithersoever thou goest.
John 12:46-49
[46] I am come a light into the world, that whosoever believeth on me should not abide in darkness.
[47] And if any man hear my words, and believe not, I judge him not: for I came not to judge the world, but to save the world.
[48] He that rejecteth me, and receiveth not my words, hath one that judgeth him: the word that I have spoken, the same shall judge him in the last day.
[49] For I have not spoken of myself; but the Father which sent me, he gave me a commandment, what I should say, and what I should speak.
Revelation 22:18-20
[18] For I testify unto every man that heareth the words of the prophecy of this book, If any man shall add unto these things, God shall add unto him the plagues that are written in this book:
[19] And if any man shall take away from the words of the book of this prophecy, God shall take away his part out of the book of life, and out of the holy city, and from the things which are written in this book.
[20] He which testifieth these things saith, Surely I come quickly. Amen. Even so, come, Lord Jesus.
God recorded His words and preserved them for thousands of years, and eventually translated His words accurately into our English language in the King James Bible, over 400 years ago. Trust that Bible. It is God's gift to us.
