Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new.

For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them.

Truly God is good to Israel, even to such as are of a clean heart.

Who can say, I have made my heart clean, I am pure from my sin?

I have seen thine adulteries, and thy neighings, the lewdness of thy whoredom, and thine abominations on the hills in the fields. Woe unto thee, O Jerusalem! wilt thou not be made clean? when shall it once be?

And I will give them one heart, and one way, that they may fear me for ever, for the good of them, and of their children after them:

And I will give them one heart, and I will put a new spirit within you; and I will take the stony heart out of their flesh, and will give them an heart of flesh:

Cast away from you all your transgressions, whereby ye have transgressed; and make you a new heart and a new spirit: for why will ye die, O house of Israel?

Then will I sprinkle clean water upon you, and ye shall be clean: from all your filthiness, and from all your idols, will I cleanse you.

And I will put my spirit within you, and cause you to walk in my statutes, and ye shall keep my judgments, and do them.

Blessed are the pure in heart: for they shall see God.

And put no difference between us and them, purifying their hearts by faith.

Seeing ye have purified your souls in obeying the truth through the Spirit unto unfeigned love of the brethren, see that ye love one another with a pure heart fervently:

And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God.

That ye put off concerning the former conversation the old man, which is corrupt according to the deceitful lusts;

And that ye put on the new man, which after God is created in righteousness and true holiness.

And have put on the new man, which is renewed in knowledge after the image of him that created him:

Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost;

And might not be as their fathers, a stubborn and rebellious generation; a generation that set not their heart aright, and whose spirit was not stedfast with God.

For their heart was not right with him, neither were they stedfast in his covenant.

Hebron therefore became the inheritance of Caleb the son of Jephunneh the Kenezite unto this day, because that he wholly followed the LORD God of Israel.

And he walked in all the sins of his father, which he had done before him: and his heart was not perfect with the LORD his God, as the heart of David his father.

Because David did that which was right in the eyes of the LORD, and turned not aside from any thing that he commanded him all the days of his life, save only in the matter of Uriah the Hittite.

Who, when he came, and had seen the grace of God, was glad, and exhorted them all, that with purpose of heart they would cleave unto the Lord.

Therefore, my beloved brethren, be ye stedfast, unmoveable, always abounding in the work of the Lord, forasmuch as ye know that your labour is not in vain in the Lord.

A double minded man is unstable in all his ways.
