I tend to agree with quafer on the subject. I think in the OT, the heart was decietful and untrustworthy. The NT has some things to say on this, most noteworthy:
1 John 2:20-23 LITV
(20) And you have an anointing from the Holy One, and you know all things.
(21) I did not write to you because you do not know the truth, but because you know it, and because every lie is not of the truth.
1 John 2:27 LITV
(27) And the anointing which you received from Him abides in you, and you have no need that anyone teach you. But as His anointing teaches you concerning all things, and is true, and is not a lie, and as He taught you, abide in Him.
This is what I am talking about. It is the living truth that is revealed into our hearts by the Spirit of God.
Some imteresting texts from the Nt abotu the heart of man.
Rom 3:9-18
9 What then? Are we better than they? Not at all; for we have already charged that both Jews and Greeks are all under sin;
10 as it is written, "THERE IS NONE RIGHTEOUS, NOT EVEN ONE;
11 THERE IS NONE WHO UNDERSTANDS, THERE IS NONE WHO SEEKS FOR GOD;
12 ALL HAVE TURNED ASIDE, TOGETHER THEY HAVE BECOME USELESS; THERE IS NONE WHO DOES GOOD, THERE IS NOT EVEN ONE."
13 "THEIR THROAT IS AN OPEN GRAVE, WITH THEIR TONGUES THEY KEEP DECEIVING," "THE POISON OF ASPS IS UNDER THEIR LIPS";
14 "WHOSE MOUTH IS FULL OF CURSING AND BITTERNESS";
15 "THEIR FEET ARE SWIFT TO SHED BLOOD,
16 DESTRUCTION AND MISERY ARE IN THEIR PATHS,
17 AND THE PATH OF PEACE THEY HAVE NOT KNOWN."
18 "THERE IS NO FEAR OF GOD BEFORE THEIR EYES."

Rom 7:15-25
15 For what I am doing, I do not understand; for I am not practicing what I {would} like to {do} but I am doing the very thing I hate.
16 But if I do the very thing I do not want {to do} I agree with the Law, {confessing} that the Law is good.
17 So now, no longer am I the one doing it, but sin which dwells in me.
18 For I know that nothing good dwells in me, that is, in my flesh; for the willing is present in me, but the doing of the good {is} not.
19 For the good that I want, I do not do, but I practice the very evil that I do not want.
20 But if I am doing the very thing I do not want, I am no longer the one doing it, but sin which dwells in me.
21 I find then the principle that evil is present in me, the one who wants to do good.
22 For I joyfully concur with the law of God in the inner man,
23 but I see a different law in the members of my body, waging war against the law of my mind and making me a prisoner of the law of sin which is in my members.
24 Wretched man that I am! Who will set me free from the body of this death?
25 Thanks be to God through Jesus Christ our Lord! So then, on the one hand I myself with my mind am serving the law of God, but on the other, with my flesh the law of sin.

Also the writers of the NT are constantly telling the Christians at the place they are writing to be steadfast in heart. Or to not sin in their heart. Surely the Nt writers understood that we still sin in our hearts even after salvation so we can't trust our hearts but only God.
