4 Bible Verses about Inner Being

Now, however, it is no longer I that do it, but sin that dwelleth in me. For I know that there dwelleth not in me, that is, in my flesh, any good thing; for to desire is present with me, but not to perform that which is good. For the good that I would, I do not; but the evil which I would not, that I do. But if I do what I would not, it is no more I that do it, but sin that dwelleth in me. I find then that there is a law to me, that when I would do good, evil is present with me.

But having the same spirit of faith, according to that which is written, "I believed, and therefore I spoke," we also believe, and therefore speak; knowing that he who raised up the Lord Jesus will raise up us also with Jesus, and will present us with you. For all things are for your sakes, that the grace abounding by means of the greater number may cause thanksgiving to abound to the glory of God. For which cause we are not fainthearted; but though our outward man is perishing, yet the inward man is renewed day by day. For our light affliction, which is but for a moment, worketh out for us, in a higher and still higher degree, an everlasting weight of glory; while we look not at the things which are seen, but at the things which are not seen; for the things which are seen are but for a time; but the things which are not seen are ever lasting.

Whose adorning, let it not be the out yard adorning of braiding the hair, and of wearing golden ornaments, or of putting on apparel; but the hidden man of the heart, in that which is imperishable, even the ornament of a meek and quiet spirit, which is in the sight of God of great price.

that he would grant you, according to the riches of his glory, to be strengthened with might by his Spirit in the inner man; that Christ may dwell in your hearts by faith, ye having been rooted and grounded in love, that ye may be able to comprehend, with all the saints, what is the breadth, and length, and depth, and height,read more.
