Kinda Childish, huh?
And said, Verily I say unto you, Except ye be converted, and become as little children, ye shall not enter into the kingdom of heaven. Whosoever therefore shall humble himself as this little child, the same is greatest in the kingdom of heaven. (Mat 18:3-4 KJV)
Oh brother. The passage you cite is a reference that we cling to Christ the way a child clings to his parents. That we rely on Christ for everything as a child relies on his parents.
Not child-like in behavior or maturity. Quite the opposite, we are told to put away childish things and to grow and mature in Christ.
Bad example - try again.
