the song "Be Thou My Vision"

 Be Thou my Vision, O Lord of my heart;

Naught be all else to me, save that Thou art
Thou my best Thought, by day or by night,
Waking or sleeping, Thy presence my light. 

Be Thou my Wisdom, and Thou my true Word;
I ever with Thee and Thou with me, Lord;
Thou my great Father, I Thy true son;

Thou in me dwelling, and I with Thee one.

Be Thou my battle Shield, Sword for the fight;
Be Thou my Dignity, Thou my Delight;
Thou my soul’s Shelter, Thou my high Tower:
Raise Thou me heavenward, O Power of my power.

Riches I heed not, nor man’s empty praise,
Thou mine Inheritance, now and always:
Thou and Thou only, first in my heart,
High King of Heaven, my Treasure Thou art.

High King of Heaven, my victory won,
May I reach Heaven’s joys, O bright Heaven’s Sun!
Heart of my own heart, whatever befall,
Still be my Vision, O Ruler of all.

The story behind the song:

 St.Patrick was born in Scotland in AD 373. He was kidnapped by pirates and was taken to Ireland as a slave, when he was 16. There he gave his heart to Jesus. Though he escaped from them, and came back home, he could never forget the encounter he had with Jesus. Then, when he was 30, he returned back to his captors and the only possession he had with him was a Latin Bible. As a result of his preaching, over 200 churches were established and 100,000 converts were baptized in Ireland.

Some scholars believed that, King Logaire of Tara, an Irish king, had decreed, that no one was allowed to light fire, until a pagan festival where the fire was lit for the pagan god. This edict restricted the lighting of candles for Easter. But St. Patrick chose to defy the King`s decree, and took a stand to honor God, even if it meant death. The King himself appreciated this act of his bravery and rendered his mission work unhindered. This song was written as a tribute on St. Patrick by Dallan Fragaill for this brave act.  

To conclude, some believe that, this song was written by St. Patrick himself and some say that it is written by Dallan Fragaill. Whatever be it, this song has always been an expression of a deep sacrifice for Christ.

But what things were gain to me, those I counted loss for Christ. Philippians 3:7

 ³⁷ Nay, in all these things we are more than conquerors through him that loved us.

³⁸ For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers, nor things present, nor things to come,

³⁹Nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus our Lord.

 Romans 8:37-39
