I will keep mine eye upon you and make you to increase. Only God can bless. Blessing is the disposition to be made of what a thing is or effects. It is the word of power of the Master of Creation. It is the promise and assurance of the Lord of Providence.
Blessing bestows a happy destiny.
Nietzsche's remark, that instead of asking favours we should confer blessings, is the saying of a rebel. He well understood his own meaning. God only can bless since God only is the master of life. By our nature we are petitioners. The contrary of blessing is cursing.
