I disagree. The heart sounds more like the conscious of a person.
The NLT is a loose translation and it changes everything away from what word for word translations say. Here is every verse from Psa 73(ESV). And the conscious is the best use of the heart.
Psalms 73:1
Truly God is good to Israel,
to those who are pure in heart.
Psalms 73:7
Their eyes swell out through fatness;
their hearts overflow with follies.
Psalms 73:13
All in vain have I kept my heart clean
and washed my hands in innocence.
Psalms 73:21
When my soul was embittered,
when I was pricked in heart,
Psalms 73:26
My flesh and my heart may fail,
but God is the strength of my heart and my portion forever.
The heart would actually involve everything that makes up your being. While emotions are included it is much more than emotions. But we also know that the heart is deceitful and desperately wicked and we do not even know it.
(Jer 17:7) Blessed
is the man that trusteth in the LORD, and whose hope the LORD is.
(Jer 17:8) For he shall be as a tree planted by the waters, and
that spreadeth out her roots by the river, and shall not see when heat cometh, but her leaf shall be green; and shall not be careful in the year of drought, neither shall cease from yielding fruit.
(Jer 17:9) The heart is deceitful above all things, and desperately wicked: who can know it?
(Jer 17:10) I the LORD search the heart,
I try the reins, even to give every man according to his ways,
and according to the fruit of his doings.
We can never trust our hearts and especially our emotions. Emotions stirred by music are often felt strongly but we would be fools to think that they define truth. The fact is that what we may be experiencing emotionally may be true but they also may not. We may be deceiving ourselves or being deceived. Our only guide and rule by which we can know truth from deception is the Word of God as opened up by the Spirit of God. When the Spirit opens the Word He shines the light in the face of Jesus Christ.
(Joh 16:13) Howbeit when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself; but whatsoever he shall hear,
that shall he speak: and he will shew you things to come.
(Joh 16:14) He shall glorify me: for he shall receive of mine, and shall shew it unto you.
(Joh 16:15) All things that the Father hath are mine: therefore said I, that he shall take of mine, and shall shew it unto you.
Satan sends his minions into churches as pastors and "Christian Colleges" as minsters of righteousness to deceive mush heads. 2Cor. 11:15 He gets people involved in dynamic equivalent translations that mislead and deceive. He is subtle and tricky. He makes everything wrong appear right because it is just shy of truth. He points people to trust their emotions and think that they see and hear Jesus. If they did ever actually see Him they would not be speaking about Him as they do.
False religion that goes by the name of "Christian" is probably the most deadly of all to the souls of men.
