Psalm 40:8

For I delight in the law of God after the inward man:

Jesus saith unto them, My meat is to do the will of him that sent me, and to finish his work.

Thy words were found, and I did eat them; and thy word was unto me the joy and rejoicing of mine heart: for I am called by thy name, O LORD God of hosts.

I will delight myself in thy statutes: I will not forget thy word.

Thy testimonies also are my delight and my counsellors.

And I will delight myself in thy commandments, which I have loved.

But this shall be the covenant that I will make with the house of Israel; After those days, saith the LORD, I will put my law in their inward parts, and write it in their hearts; and will be their God, and they shall be my people.

Unless thy law had been my delights, I should then have perished in mine affliction.

My son, forget not my law; but let thine heart keep my commandments:

Praise ye the LORD. Blessed is the man that feareth the LORD, that delighteth greatly in his commandments.

Forasmuch as ye are manifestly declared to be the epistle of Christ ministered by us, written not with ink, but with the Spirit of the living God; not in tables of stone, but in fleshy tables of the heart.

Neither have I gone back from the commandment of his lips; I have esteemed the words of his mouth more than my necessary food.

For whom he did foreknow, he also did predestinate to be conformed to the image of his Son, that he might be the firstborn among many brethren.
