Christian Maturity

It is clear that John the apostle does not want the Christian community to be content with sloppy Christianity.

"The Bible is the means God uses to complete us, to finish us, to bring us to maturity."

What makes a mature man? The humility it takes to receive correction from other people is the same humility it takes to receive correction from God, and visa versa. That is why the ability to absorb correction is one of the key marks of being mature.
