6 Bible Verses about Inner Being

For we know that the law is spiritual, but I am carnal, having been sold under sin. For I do not understand what I do, for I do not do this that I want, but what I hate, this I do. But if I do this that I do not want, I agree with the law that it is good.read more.
But now I no longer perform it, but the sin dwelling in me. For I know that good does not dwell in me, that is, in my flesh, for to will is present in me, but to do the good, I find not. For I do not do good that I want, instead, wrong that I do not want, this I do. But if I do this that I do not want, I no longer perform it, but sin dwelling in me. Consequently I find the law in my wanting to do good, that evil is present in me. For I delight in the law of God according to the inner man, but I see a different law in my body-parts, warring against the law of my mind, and taking me captive in the law of sin, which is in my body-parts.

And having the same spirit of faith, according to that which is written, I believed, therefore I spoke, we also believe, and therefore we speak, knowing that he who raised up the Lord Jesus will also raise us up through Jesus, and will present us with you. For all things are for your sakes, so that the grace, which has multiplied because of the thankfulness of the many, may abound for the glory of God. Therefore we are not discouraged, but even if the outer man of us is perishing, yet the inner man is renewed day by day. For our slight momentary affliction works for us an eternal weight of glory from extraordinariness to extraordinariness, while we look not at things seen, but at things not seen. For things seen are temporal, but things not seen are eternal.
