Ecclesiastes 12:13-14 KJV
Let us hear the conclusion of the whole matter: Fear God, and keep his commandments: for this is the whole duty of man. [14] For God shall bring every work into judgment, with every secret thing, whether it be good, or whether it be evil.

Matthew 5:19 KJV
Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven.

Revelation 22:12,14-15,19-20 KJV
And, behold, I come quickly; and my reward is with me, to give every man according as his work shall be. [14] Blessed are they that do his commandments, that they may have right to the tree of life, and may enter in through the gates into the city. [15] For without are dogs, and sorcerers, and whoremongers, and murderers, and idolaters, and whosoever loveth and maketh a lie. [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.
