Materialistic things are not blessings. Yes they are nice to have but they shouldn't be referred to as blessings. Blessings are more natural. Breathing fresh air is a blessing. Admiring the beauty of a delicate bird is a blessing.
Being able to use the will power given to us by our Creator, to obtain our goals is a blessing. The nice things are simply a result of that blessing.
I say this because what constitutes a rich kid getting blessed over a poor kid. Who is more deserving of the blessing? Both children rich or poor are blessed with the gift of laughter and imagination.
Blessings are bestowed upon us daily. We just need to appreciate them. Remember your will power is a blessing within itself. When we work in tandem with the creator within us, we are blessed.
