I would think constant prayer and attention to God and giving up worldly possesions is quite scriptural. As for preserving and spreading the faith, I think Monastics have accomplished a great deal. The Desert Fathers and Mt. Athos come to mind but there are many more.
Shutting down the monasteries was a great loss for the Reformers. They lost a large part of the heart of their religion, IMHO. Making their Christianity more intellectual and rational, if you will, was a move in the wrong direction I believe.
If God has called you to give up worldly possessions yes, but to gain some special favor for what a good boy you were, no.
Christianity is not a "stay away" religion. There are moments in time where one may retreat for a while. But a life of retreating from society is not found in the New Testament anywhere that I have seen.
Rather, Jesus's words were
Mark 16: 15And he said unto them, Go ye into all the world, and preach the gospel to every creature.
And Matthew 28: 19Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:
And Acts 1: 8But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth.
And Matthew 5:13Ye are the salt of the earth: but if the salt have lost his savour, wherewith shall it be salted? it is thenceforth good for nothing, but to be cast out, and to be trodden under foot of men. 14Ye are the light of the world. A city that is set on an hill cannot be hid. 15Neither do men light a candle, and put it under a bushel, but on a candlestick; and it giveth light unto all that are in the house. 16Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven.
