The Ekklesia enjoys spiritual oneness with Jesus, and so it grows spiritually (and may I say it grows spontaneously) without effort, and is fruitful as it continues to abide in that spiritual oneness that already exists in Christ.
“Spiritual growth is not more knowledge or increase of years. It is simply more of Him and less of me. He increases as I decrease. This is what it means to be a disciple.” – Chip Brogden
