After convincing a professed Christian that growth takes work, you will probably then have to convince them that spiritual growth is necessary.
Necessary for what? For salvation. If there is no spiritual growth there is no salvation.
Now, here is again where most Christian types will flip out, “Are you saying that in order to be saved I have to grow? Are only mature people in heaven? I have to fix myself before God will save me, is that what you’re saying?”
Nope, it’s not. What I said was: “If there is no spiritual growth there is no salvation.”
Spiritual growth does not save a person. You cannot have spiritual growth unless you are a spiritual creation. Being saved will result in spiritual growth.
“But wait, you just got done saying yesterday that “spiritual growth is not automatic, that I have to work at it.” Make up your mind bozo.”
Exactly! Physical maturity takes work. Little babies have to eat and use their little muscles to learn to get around and figure out life. You gotta do something. Babies don’t just pop out and grow to maturity without doing anything.
“As newborn babes, desire the sincere milk of the word, that ye may grow thereby.”
If we do not desire the word we won’t grow. Growth takes some effort. If you aren’t reading the Word, you probably aren’t saved, this is the believer’s lifeblood of spiritual health. If you aren’t being transformed by the Word you probably aren’t saved.
Pretty harsh words. I imagine the works-righteousness accusation is about to be flung at me again. So I’ll let Paul say it instead, “the word of God, which effectually worketh also in you that believe.”
The Word of God has power with the believer. If there is no demonstration of power from the Word in a person, that person should doubt they are saved.
Claiming to be spiritually alive and yet having no growth makes as much sense as a person who claims to be a runner who doesn’t run. A piano player who never plays piano. A carpenter who has never touched wood.
We are not saved by growth; we are saved by faith. The result of being saved, every single time, is that there will be spiritual growth. No growth? Then there’s no life.
