v1 - God be gracious to us and bless us, {And} cause His face to shine upon us-- Selah.
v2 - That Your way may be known on the earth, Your salvation among all nations.
... ... ...
v7 - God blesses us, That all the ends of the earth may fear Him.
It is right to ask God to bless you. Especially when your motivation is that he be glorified in doing so. This is not the same as the health and wealth gospel, and wanting stuff, and comfort. This is asking God to pour out spiritual blessing, so that even if we are physically "put to death all day long" we will have a hope and spiritual abundance, and a living gospel that causes others to see and turn to God.
Think about the book of Acts. The church was persecuted and scattered; yet God was causing his face to shine upon them so much that gentiles were turning from idols to serve the one true God.
Let these verses give you courage to pray, specifically asking that God would bless your life and so fill you with faith and the Holy Spirit that those around you would be converted (to the praise of the glory of his grace).
