3 Bible Verses about Inner Being

For we know that the law is spiritual: but I am carnal, having been sold under sin. For that which I do, I know not: for I do that which I do not will; but I do that which I hate. But if I do that which I do not will, I consent to the law that it is beautiful;read more.
but now it is no more I that do it, but sin dwelling in me. For I know that in me, that is, in my carnal mind, there dwells no good thing. For to will is present with me, but to do that which is beautiful is not: for the good which I will I do not; but the evil which I do not will, that I do. If I do that which I do not will, it is no longer I that do it, but sin dwelling in me. Then I find a law, that, to me wishing to do that which is beautiful, that the evil is present with me: for I delight in the law of God according to the inward man; but I see another law in my members, warring against the law of my mind, and bringing me into captivity to the law of sin which is in my members. O wretched man that I am! who shall deliver me from the body of this death? Thanks be unto God through Jesus Christ our Lord: then therefore with the mind I serve the law of God; but with carnality the law of sin.

But having the same spirit of faith, according to that which has been written, I believed, therefore I also spoke; and we believe, therefore we also speak; knowing that the one having raised up the Lord Jesus will also raise us along with Jesus, and present us with you. For all things are for your sakes, in order that the grace, overflowing with thanksgiving through many, may abound unto the glory of God. Therefore we faint not; but if indeed our external man perishes, yet our internal man is renewed day by day. For the light burden of our affliction, which is evanescent, is working out for us an eternal weight of glory according to hyperbole unto hyperbole; we not looking at the things which are visible, but the things which are invisible; for the visible things are temporary, but the invisible things are eternal.

whose beauty, let it not be the external beauty of braiding the hairs, and wearing golds, or putting on of outer garments; but let their beauty be the hidden man of the heart, in the purity of the meek and quiet spirit, which in the sight of God is perfection complete.
