I wonder if a heart can also be likened to a mountain...  In that, even a person can be likened to a mountain.

Psalm 15 -- LORD, who can dwell in Your tent?
    Who can live on Your holy mountain?
    The one who lives honestly, practices righteousness,
    and acknowledges the truth in his heart —
    who does not slander with his tongue,
    who does not harm his friend
    or discredit his neighbor,
    who despises the one rejected by the LORD,
    but honors those who fear the LORD,
    who keeps his word whatever the cost,
    who does not lend his money at interest
    or take a bribe against the innocent —
    the one who does these things will never be moved.

There is a lot here.  Each word has deep meaning, and there is much "between the lines."

One such deep meaning is honoring those who fear the LORD.  In this, those who fear the LORD are also wise, because the beginning of Wisdom is fear of Father Yahweh.  Then, that can even be extended to those children who, although are so young, are very wise if they fear Father.  If oneself even honors children, there can even be humility.  In this, honoring a child could even extend to keeping one's promises towards them, or helping them with anything that they seek help with.  If a child who fears Father asks a request, or question, for oneself to lower themselves to help the child along shows great love and compassion.

Slandering with the tongue...  Combine that with James 3:1-12.

Moreover, one pollutes their whole self with their words, if they even think them outwards.  Words can come from even thoughts.  Even if oneself thought that they feel okay at first, there is still much more to move forward in.  One shouldn't become complacent.  It does upset to hear that negative speech is "scientifically studied" to help whatever...or for it to ever be condoned.  Yet, it does happen.  If one speaks out of the overflow of their heart, and what one speaks can cause further deterioration or uplifting of their heart, one must be very cautious to see that what they speak is not out of their own heart, but out of Father's Spirit within one's heart, so that it if Father's Spirit that grows.  Again, though, it is not good for oneself to not speak or not think, because that would either to be complacent, or wrongfully afraid.  It stops the good that could be done, and in the error of what one speaks, they should seek Father with a whole and true heart.

Proverbs 10:19 -- When there are many words, sin is unavoidable, but the one who controls his lips is wise.

Faith without works is dead, and if one considers their words to include their works, one must speak in light of Father's faith that is in one's heart.

Acknowledging the Truth within one's heart.  Inclusive of Father, Christ, and all that is really going on around oneself.  As it has been said, things are not just as they seem.

Not harming their friend or discrediting their neighbor.  In this, one's friend and neighbor can also be Father, Christ, and all of Father's positive creation.  At the same time, it includes those who are friends that one may not even know, or those who are neighbors that one does not have any imagination they are close to.  One can discover more about who one's neighbor is given by scripture, especially including what Christ shared here: Luke 10:25-37.

Despising the one rejected by Father.  Self explanatory, BUT, judgment was handed to Christ.  Thus, of those whom are known that are rejected, not included amongst them are humans that are still in the physical plane on the planet at the current time...there is...still an inkling of hope, and even faith the size of a mustard seed can grow to a large tree.  There are commands about certain things, and to those things a person must adhere to.

Keeping one's word whatever the cost.  Thus, even what one says is an oath of sorts.  One doesn't have to have certain phrases ahead of time in order to make an oath or promise, and as such, what one says that they will do, they must.  However, oneself does not know whether they will be able to or not, and so they must base their words on Father.

James 4:13-17 -- Come now, you who say, "Today or tomorrow we will travel to such and such a city and spend a year there and do business and make a profit."  You don't even know what tomorrow will bring—what your life will be! For you are a bit of smoke that appears for a little while, then vanishes.  Instead, you should say, "If the Lord wills, we will live and do this or that."  But as it is, you boast in your arrogance. All such boasting is evil.  So, for the person who knows to do good and doesn't do it, it is a sin.

As well, there is a sense of nobility and...well...even chivalry...in keeping one's word.  This correlates with the following:

Proverbs 8:6 -- Listen, for I speak of noble things, and what my lips say is right.

Not making lends with interest...one can lend their wisdom and not expect anything in return.  One can provide their coat and not expect another to give it back.  One can give their pens and paper, their very own service, and not expect anything in return.  In this, oneself should be willing to give, and not for reasons.  Just as oneself doesn't have to have a reason to do something good.

Not taking a bribe against the innocent.  Perhaps the first thing that may come to mind is that one wouldn't accept blood money.  However, this would include perversion of justice, or anything else.  Bribery doesn't have to include money.  In fact, a bribe should not even be heard of amongst people.  Yet, it still occurs.  In addition, this does not mean one should or it is acceptable to take bribes against the guilty.  That doesn't make much sense...  There is much more here, and there is a structure, but...I cannot see it as of yet.

There is a structure in this whole psalm, actually...much like atomic particles, and it can go smaller and smaller.  It also can get bigger and bigger, and can be joined with other scriptures to produce...well...more energy.  Mirrors atomic energy...  Father's Word holds all answers.

Living honestly and practices righteousness.  This is similar and can be used in conjunction with not having to have a reason to do something good.  At the same time, being integrable.  Practicing righteousness is also...exactly what it says.  As an infant in Father's Spirit, there is an amount of protection necessary to fully mature, and if one takes a potentially lethal blow, there is protection that must be made to wounds.  In a strong way, the two points are strongly intertwined.

Now, for one to not be moved.  If one lives on Father's mountain, they have the foundation of a rock that can even, in some circumstances, help oneself to be able to weather all kinds of storms and disasters.  It goes further than that, too.  Consider if one lived on the mountain that Father provided the ten commandments.  One would be in utter fear of Father's awesome power on the mountain.  But in that fear, would one be moved in the wrong way?  If they do not hold to their honest living and practicing righteousness, they might run.  In this, to understand Father's Wisdom is to understand what is at the heart of what Father is saying.  This, perhaps, is why Father's Word can be a mystery.  Without Father's guidance, without Her love, righteousness, mercy, patience, Wisdom, and every good thing, scripture won't make sense.  It was noted that a lot of Father's Word is "sketchy on exactly what happens in between one fulfillment of prophecy to that of the next,"  and as such, being able to follow Father's Light to discover the gems of Father's Wisdom and Truth can be just as difficult.

By this, one must also be careful in trying to piece together different parts of scripture.  There might be words that blaspheme Father and say that scripture doesn't...well, it's difficult to even share what evil can be said...  It is known that Father's scripture matches up correctly, and Father's Word correlates all together, like the complete working body of a perfect Creation of Father's.  As such, anything that does not correlate with that Truth is a lie, because anything that does not mix with what is Truth that is known that is True, cannot be True also.  Certain things will make sense "right off the bat", but a person must not lose sight of Father's Truth in one's heart by becoming confused with falsehoods or mismatched pieces.  If one thing doesn't fit correctly, it must not be leaned upon until it seems to fit, or it will fall apart, and oneself perhaps with it if Father is not there to support oneself.  If one seeks Wisdom, they can wait for Father for it.  Hope in Father does not disappoint.
