"To Be Established"

[A Psalm of David] "LORD, who shall abide in Thy tabernacle? who shall dwell in Thy holly hill?" (Psalms 15:1) Some days you just feel unworthy! When we weigh the things of fame and fortune against the subtle ways of God, we begin to see ourselves at odds with both worlds; feeling sometimes as though we have no place in either, we can look to establish a place where we know that we belong. Don't get me wrong; because this is not necessarily a bad thing; to evaluate our character, is something that we should be willing to do; because, without the ability to examine our own hearts, we never stand to be corrected. What we have here in this verse, is not a question of who it will be, but rather, what is the character of those that will be established in God's kingdom; in other words, What is required to become a citizen of heaven? I do not believe that this is something to be asked once, and then to move on as if you have the answer, because we all are subject to change and require adjustments in our thinking, or in the condition of our hearts. It is only natural for us to take on certain qualities of those which whom we live and communicate with on a daily basis; therefore, we need to be reminded of what a citizen of heaven looks like, seeing that we are dwelling in a foreign land, and can be tainted by that which we accustom to seeing and hearing. In regards to the introduction of this Psalm, and whether or not it has meaning; I am willing to say that it has something to do with the self-evaluation; which is not set to certain music, because the mood sets the tempo and the melody of the song which is being sung. In other words; depending on what side of citizenship you are on, or find yourself dwelling in, your mood can be greatly affected, which could greatly alter the song that is sung. I look again at the 'Rich Young Ruler', who came to Jesus with anticipation of receiving good news about "How to inherit eternal life?", and went away feeling sad and unworthy of obtaining it; not because he could not, but rather, because he cared more about something else at that moment, which were his riches...
