Thank you for the interesting question! And for your comment in the beginning of the post! (I thought I've been talking to myself for at least the last ten pages!

)
The second comment you make about me 'just bumping the thread' is inaccurate, however. I assure you my goal is not to "just bump" this thread (I would have simply wrote 'bump' like I always do), but rather to share with all my friends here some beautiful and profound quotes about God's love and how we can find it.
I admit, the posts at times have been all over the place. But the main theme I wished to keep was the theme of our duties as Christians and the suffering and sacrifice required to crucify our own passions and put on Christ our God.
The main point I started out the thread was on forgiveness and love of our enemies. From there it spread to other themes in the same vein, such as mercy, charity, etc.).
But anyway, that I hope answers some of your questions.
As for the other excellent questions:
what's your take on the journey towards each form of love (agape, storge, eros, phileo) and at what point would one achieve a godly degree of love? Is there even an achievable destination to this journey?
The Holy Fathers of the Church describe three types of love and not four (although the three do include what the fourth is). Namely, agape, eros and philia.
Here is a short summation:
The first definition of love as agape is love as the action of perfect goodness for the sake of the other. This is the most basic meaning of love: to do everything possible for the well-being of others. God Himself has this love as the very content of His being and life, for “God is agape.” It is with this love that spiritual per- sons must love first of all.
The second definition of love as eros is love for the sake of union with the other. Erotic love is no sin when it is free from sinful passions. It can be the utterly pure desire for communion with the other, including God. All spiritual writers have insisted that such love should exist between God and man as the pattern for all erotic love in the world between husband and wife. (See Sexuality, Marriage, and Family) Thus the mystical writers and spiritual fathers have used the Old Testament’s Song of Songs as the poetic image of God’s love for man and man’s love for God. (Philo the Jew, Gregory of Nyssa, Bernard of Clairvaux, John of the Cross, Richard Rolle in England, et al.) Indeed the prophets have used the image of erotic love in explaining the Lord’s relation with Israel. (Isaiah 54; Jeremiah 2-3,31; Ezekiel 16; Hosea) And Saint Paul uses this image for Christ’s love of the Church. (Ephesians 6) In the scriptures, the union of man with the Lord in the Kingdom of God is primarily revealed in the image of eros. (Matthew 22, Revelation 19-22)
...for the marriage of the Lamb has come, and His Bride has made herself ready; it was granted to her to be clothed with fine linen, bright and pure - for the fine linen is the righteous deeds of the saints. (Revelation 19:7-8)
“Come, I will show you the Bride, the wife of the Lamb.” (Revelation 21:9)
The third type of love is friendship - phila. This also should exist between man and God. Man has no greater friend than God, and God Himself wants to be man’s friend. According to the scriptures, the very purpose of the coming of Christ was to dispel all enmity between God and man, and to establish the co-working of Creator and creature in the fellowship of friendship.
Thus the Lord used to speak to Moses face to face, as a man speaks to his friend. (Exodus 33:11)
Greater love has no man than this, that he lay down his life for his friends. You are my friends if you do what I command you. No longer do I call you servants (or slaves), for the servant does not know what his master is doing. But I have called you friends, for all that I have heard from my Father, I have made known to you. (John 15: 13-15)
So it is that love as goodness, love as union, love as friendship are all to be found in God and man, between God and man, and between human beings. There is no form of true love which lays outside the realm of the spiritual life.
In summation: The Kingdom of Heaven is our destination, for this is what God has prepared for those who love Him. And this love we strive for and live for. It is the love we we find power from and strength in. To reach it, we must make it a journey of love! For this is the way Christ taught us! This is the way to God and union with God. It is the way of redemption and salvation!
