The only angels we need invoke are those of our better nature: reason, honesty, and love. The only demons we must fear are those that lurk inside every human mind: ignorance, hatred, greed, and faith, which is surely the devil's masterpiece.
When all is said and done, the greatest satisfaction you'll have in this life as you grow old will be seeing your children grow in righteousness and faith and goodness as citizens of the society of which they are a part.
