Jesus wants his followers to produce good fruit. Fruit of the Spirit, typically. It’s proof of our salvation: If we really do have the Holy Spirit within, if we really do abide in Christ, if we really have a relationship with our Father, we’re gonna be fruity.
No, not automatically, despite what some Christians claim. I know; I’ve heard their testimonies. “All of a sudden I just stopped sinning! It’s amazing!” No; at most the Spirit broke some addictions, but you chose to listen to the Spirit instead of your flesh. You chose to resist temptation instead of getting deterministically reprogrammed to follow God instead of your id. Fruit doesn’t spontaneously happen. It’s the product of a relationship—the one we often claim we have instead of religion—in which the Spirit leads and we follow. Most of the time it’s way easier than we ever expected (’cause the Spirit empowers us), and the more we do it the easier it gets, but still: Both of us do it.
And then there are the Christians who aren’t fruity. They’re fleshly.
No doubt you’ve met a few. Are related to a few. They aren’t loving. They’re joyless. Quickly irritated, angered, outraged, offended. Impatient. Out-of-control emotions. They do all sorts of evil things, ranging from white lies to full-on criminal activity, and justify it all sorts of ways. They claim they trust God, but more often trust their wallets, friends, political parties, media, and some stranger they found on the internet who tells it just the way they like it. They know it all; you can’t tell ’em different. They have no self-control, as you can tell from their debts, waistline, constant tardiness, and inability to let others reply, or have the last word. They haven’t crucified the flesh; Ga 5.24 in many cases they’re even saying God wants them to indulge themselves, because didn’t he make this world for us to enjoy?
Fruit isn’t their litmus test for Christianity. They came up with substitutes. They’re looking for orthodoxy, conformity, niceness, zealousness, baptism, whether you said the sinner’s prayer, whether you’re in a bible-believing church, the right politics, the right vocabulary. And sometimes they’re looking for nothing, and accept you’re Christian entirely because you say you are.
They get outraged when I suggest certain self-described “Christians,” who nonetheless demonstrate none of the Spirit’s fruit soever, are not.
As I said, fruit isn’t their litmus test. I claim it is; they claim it can’t be. Because they’ve never remotely thought of fruit that way. Fruit’s just a nice idea; the Galatians verses are just a nice passage to memorize; and when Jesus talked about fruit he was only talking about false prophets, Mt 7.15-16 and not all of us are prophets. Their churches claim one of the other unscriptural litmus tests, like a sinner’s prayer, and denouncing Satan at one’s water baptism.
And hey, what about newbies? If a person’s just become Christian a month ago, or six months ago, should we expect a “baby Christian” to exhibit the Spirit’s fruit to the level of a mature Christian? That’s ridiculous. They’re too new! Besides, even the spiritually mature Christians they know are occasionally, if not frequently, deficient in love, joy, peace, patience, and grace.
And whenever they point to the “mature Christians” they know with frequent lapses of fruit, you begin to realize exactly why they never remotely thought of fruit as evidence of one’s Christianity.
