Be All the More Eager to Make Your Calling and Election Sure

5For this very reason, make every effort to add to your faith goodness; and to goodness, knowledge; 6and to knowledge, self-control; and to self-control, perseverance; and to perseverance, godliness; 7and to godliness, brotherly kindness; and to brotherly kindness, love. 8For if you possess these qualities in increasing measure, they will keep you from being ineffective and unproductive in your knowledge of our Lord Jesus Christ. 9But if anyone does not have them, he is nearsighted and blind, and has forgotten that he has been cleansed from his past sins.
10Therefore, my brothers, be all the more eager to make your calling and election sure. For if you do these things, you will never fall, 11and you will receive a rich welcome into the eternal kingdom of our Lord and Savior Jesus Christ.

Faith-------------------------------------The Foundation

It appears that all of the qualities we need to posses are built up on the foundation of faith. From faith we see levels of refinement with the highest level of achievement being love, the way Jesus defines it:

1 Corinthians 13:3-5 (New International Version)
3If I give all I possess to the poor and surrender my body to the flames,[a] but have not love, I gain nothing.
4Love is patient, love is kind. It does not envy, it does not boast, it is not proud. 5It is not rude, it is not self-seeking, it is not easily angered, it keeps no record of wrongs.
3If I give all I possess to the poor and surrender my body to the flames,[a] but have not love, I gain nothing.
4Love is patient, love is kind. It does not envy, it does not boast, it is not proud. 5It is not rude, it is not self-seeking, it is not easily angered, it keeps no record of wrongs.
3If I give all I possess to the poor and surrender my body to the flames,[a] but have not love, I gain nothing.
4Love is patient, love is kind. It does not envy, it does not boast, it is not proud. 5It is not rude, it is not self-seeking, it is not easily angered, it keeps no record of wrongs.

To him Who Overcomes

Revelation 2
7He who has an ear, let him hear what the Spirit says to the churches. To him who overcomes, I will give the right to eat from the tree of life, which is in the paradise of God.

11He who has an ear, let him hear what the Spirit says to the churches. He who overcomes will not be hurt at all by the second death.

17He who has an ear, let him hear what the Spirit says to the churches. To him who overcomes, I will give some of the hidden manna. I will also give him a white stone with a new name written on it, known only to him who receives it.

26To him who overcomes and does my will to the end, I will give authority over the nations— 27'He will rule them with an iron scepter; he will dash them to pieces like pottery'[b]— just as I have received authority from my Father. 28I will also give him the morning star. 29He who has an ear, let him hear what the Spirit says to the churches.

Revelation 3

5He who overcomes will, like them, be dressed in white. I will never blot out his name from the book of life, but will acknowledge his name before my Father and his angels. 6He who has an ear, let him hear what the Spirit says to the churches.

12Him who overcomes I will make a pillar in the temple of my God. Never again will he leave it. I will write on him the name of my God and the name of the city of my God, the new Jerusalem, which is coming down out of heaven from my God; and I will also write on him my new name. 13He who has an ear, let him hear what the Spirit says to the churches.

21To him who overcomes, I will give the right to sit with me on my throne, just as I overcame and sat down with my Father on his throne. 22He who has an ear, let him hear what the Spirit says to the churches."
