You're blessed because you're trusted to bless someone else, Its not just about you, Its about being a steward of Gods blessings, You could be the answer to someones prayer, Its not even about monetary issues, Sometimes its just about giving your time and friendship, Making someone feel and know they're loved. Life itself is a blessing so giving your time in a good way is also passing on the blessing.
A blessing is a blessing in the sense that if it rains upon you,you should spread it to others for them to be blessed too.
