Bush beans grow beans. Therefore, we know certain plants will always produce certain types of fruit. Christians are born of the Spirit and bear His spiritual genetic code. This means we should have the same traits developing in us that already exist in perfection in Him. Our values, perspectives and character should be like His . . .
Fruit means reproduction.
A corn stalk produces several ears of corn loaded with hundreds of kernels. Each kernel has the potential to produce another corn stalk. Like produces like. So we as Christians must contribute our part to the production of more Christians. I am too haphazard about fruit production in my life.
