Patrick loved the people of Ireland more than he loved his own life.  He had a passion to witness to them for all of his life even if it resulted in his losing his life.
I suspect there is a mission field for every Christian.  There are people who God places on our heart.  We can choose to live to love those people, sharing Christ with them.  Or we can busy ourselves with work, and pleasure making room for those God has given us only when it is convenient.

. But what should I say, or what should I promise to my Lord, for I, alone, can do nothing unless he himself vouchsafe it to me.

But let him search my heart and nature, for I crave enough for it, even too much, and I am ready for him to grant me that I drink of his chalice, as he has granted to others who love him.

Therefore may it never befall me to be separated by my God from his people whom he has won in this most remote land.

I pray God that he gives me perseverance, and that he will deign that I should be a faithful witness for his sake right up to the time of my passing.

And if at any time I managed anything of good for the sake of my God whom I love, I beg of him that he grant it to me to shed my blood for his name with proselytes and captives, even should I be left unburied, or even were my wretched body to be torn limb from limb by dogs or savage beasts, or were it to be devoured by the birds of the air, I think, most surely, were this to have happened to me, I had saved both my soul and my body.

For beyond any doubt on that day we shall rise again in the brightness of the sun, that is, in the glory of Christ Jesus our Redeemer, as children of the living God and co-heirs of Christ, made in his image; for we shall reign through him and for him and in him.

For the sun we see rises each day for us at [his] command, but it will never reign, neither will its splendor last, but all who worship it will come wretchedly to punishment. We, on the other hand, shall not die, who believe in and worship the true sun, Christ, who will never die, no more shall he die who has done Christ’s will, but will abide for ever just as Christ abides for ever, who reigns with God the Father Almighty and with the Holy Spirit before the beginning of time and now and for ever and ever. Amen.
