4 Bible Verses about Inner Being

We know that the Law is spiritual, but I am earthly-sold into slavery to Sin. I do not understand my own actions. For I am so far from habitually doing what I want to do, that I find myself doing the very thing that I hate. But when I do what I want not to do, I am admitting that the Law is right.read more.
This being so, the action is no longer my own, but that of Sin which is within me. I know that there is nothing good in me-I mean in my earthly nature. For, although it is easy for me to want to do right, to act rightly is not easy. I fail to do the good thing that I want to do, but the bad thing that I want not to do-that I habitually do. But, when I do the very thing that I want not to do, the action is no longer my own, but that of Sin which is within me. This, then, is the law that I find-When I want to do right, wrong presents itself! At heart I delight in the Law of God; But throughout my body I see a different law, one which is in conflict with the law accepted by my reason, and which endeavors to make me a prisoner to that law of Sin which exists throughout my body. Miserable man that I am! Who will deliver me from the body that is bringing me to this Death? Thank God, there is deliverance through Jesus Christ, our Lord! Well then, for myself, with my reason I serve the Law of God, but with my earthly nature the Law of Sin.

This treasure we have in these earthen vessels, that its all- prevailing power may be seen to come from God, and not to be our own. Though hard pressed on every side, we are never hemmed in; through perplexed, never driven to despair; Though pursued, never abandoned; though struck down, never killed!read more.
We always bear on our bodies the marks of the death that Jesus died, so that the Life also of Jesus may be exhibited in our bodies. Indeed, we who still live are continually being given over to death for Jesus' sake, so that the Life also of Jesus may be exhibited in our mortal nature. And so, while death is at work within us, Life is at work within you. But, in the same spirit of faith as that expressed in the words--'I believed, and therefore I spoke,' we, also believe, and therefore speak. For we know that he who raised the Lord Jesus will raise us also with him, and will bring us, with you, into his presence. For all this is for your sakes, that the loving-kindness of God, spreading from heart to heart, may cause yet more hearts to overflow with thanksgiving, to his glory. Therefore, as I said, we do not lose heart. No, even though outwardly we are wasting away, yet inwardly we are being renewed day by day. The light burden of our momentary trouble is preparing for us, in measure transcending thought, a weight of imperishable glory; We, all the while, gazing not on what is seen, but on what is unseen; for what is seen is transient, but what is unseen is imperishable.

Yours should be, not the external adornment of the arrangement of the hair, the wearing of jewelry, or the putting on of dresses, but the inner life with the imperishable beauty of a quiet and gentle spirit; for this is very precious in God's sight.

And pray that, in proportion to the wealth of his glory, he will strengthen you with his power by breathing his Spirit into your inmost soul, So that the Christ, through your faith, may make his home within your hearts in love; And I pray that you, now firmly rooted and established, may, with all Christ's People, Have the power to comprehend in all its width and length and height and depth,read more.
And to understand--though it surpasses all understanding--the love of the Christ; and so be filled to the full with God himself.
