From Mere Christianity, by C.S. Lewis:
"...Christ never meant that we were to remain children in intelligence: on the contrary, He told us to be not only "as harmless as doves," but also "as wise as serpents." He wants a child's heart, but a grown-up's head.
He wants us to be simple, single-minded, affectionate, and teachable, as good children are; but He also wants every bit of intelligence we have to be alert at its job, and in first class fighting trim."
I like that: a child's heart, but a grown-up's head.
Loving, forgiving, trusting; smart, confident, mature.
Being someone who knows to plan ahead, but also be spontaneous.
Knowing how to get along with others, without letting others negatively influence you.
Transparent and honest, but also tactful and wise.
Hmm. Good thing God promised us help with that.
