“The land produced vegetation: plants bearing seed according to their kinds and trees bearing fruit with seed in it according to their kinds. And God saw that it was good.” (Genesis 1:12)
A type of fruit completely depends on the type of tree it comes from. Barrenness is always considered a curse. The spiritual fruit in my life directly reflects my condition (my lineage), where I am rooted. Therefore, the fruit I bear completely depends on my spiritual development. The quantitive growth of a church is an indicator of the quality of growth of its team of ministers.
