Spiritual maturity is not possessing vast quantities of Bible knowledge or possessing the most powerful spiritual gifts. Carnal people can have both of these things. Spiritual maturity is sharing the affections of God and discerning his voice. It is loving what God loves and hating what he hates. Spiritually mature Christians love God and his people passionately, and they hate anything that takes them away from God. Only in the context of such love will Bible knowledge and the gifts of the Spirit ever achieve their divine purposes. The power of the Spirit can flow unhindered through passionate love for God and his children
