We often view salvation as a one-and-done experience. This verse casts doubt on that assumption. But what does Paul mean by "work out your salvation," and how do we apply it? I believe much of it comes down to making all the aspects of the gospel fit together, without neglecting anything. For example, the current church seems to be split on whether forgiveness or obedience is more important. But if we want to experience that promised ever-increasing glory, we must recognize that they depend on one another. (2 Cor. 3:18) So no one side is more important than the other.
For example, the legalist who is all about obedience. While they may recognize that we need God’s grace to wipe the slate clean so that we may start over as flawless. However, they are hesitant to offer any more forgiveness beyond that. Never allowing that "safe space" to stumble and skin our proverbial knees from time to time as we learn to walk with Jesus. If they had worked out their salvation themselves, they would have dealt with that plank in their own eye. Then they would know how to assist others in their walk of salvation, instead of just condemning and criticizing them for their failures. (Matt 7:3-5) Clearly, they have only whitewashed their hearts in their own strength to avoid judgment (Matt 23:27-28) rather than be vulnerable with their own brokenness. In the end, obedience-centered churches only teach each other how to repeatedly whitewash the cracks that keep coming back to the surface. This is not the path that leads to fulfilling his "good purposes." Consider this: the verses above are part of a broader passage about Christ-like humility, something most legalists lack. Plus, Paul acknowledges that they were already obedient. Yet apparently obedience alone did not make their salvation complete.
This more recent phenomenon of grace-centered churches is a response to the legalists. They recognized the problem, only to overcorrect. Often getting into an endless cycle of failing in the same way, but never learning anything from it. This frequent backsliding often leads to completely ignoring righteousness and obedience altogether. Putting the forgiveness that they are so grateful for on a pedestal, but never using it for its intended purpose. To start over with Godly wisdom and strength that leads to more consistency. That eventually leads to the glory of being set apart for his "good purposes."
Ultimately, the church needs to be a place of support where we can work out our salvation, inevitable falls, immature beliefs, and all. (Romans 14) Since experience is often the best teacher, with the Lord directing our steps and all. (Proverbs 16:9) But do we allow the church to be that? More often than not, we see opposite extremism. All because we want to control our own path, and the paths of others. A course that tries to take shortcuts around the sensitive issues we would just assume avoid.
The grace extremists seem to want just enough salvation to keep them out of hell, but nothing more. They don’t want anything interfering with their own plan for prosperity. Including letting go of the sinful emotional pain-killers they use to mask the brokenness that they don’t want to face. But is obviously holding them back. When the chips are down, they just won’t put their heart on the line for any kind of transformation, let alone service. (Romans 12:2)
Where the obedience extremists are too caught up in their Old Testament frame of mind. Do what I say that God says, or be destroyed. This only feeds their pride, self-righteousness, superiority complex, and their desire to seek and condemn the lost. They don't want to get involved in the messy lives of others, since it reveals the whitewash over their own mess. Try reading all of Matthew 23. The average legalist has made so many of the same mistakes that the Pharisees did. Proving they are not nearly as righteous or obedient as they claim. That they fail in their own rigid Biblical standard, and show they need the additional grace that they deny others.
This isn't even the half of it. The fact of the matter is, many churches have plateaued in their spiritual immaturity. Stuck in the incomplete foundational truths of the gospel. Unsuitable for building his "good purposes" upon. (Hebrews 6:1) Yet we wonder why the church seems so powerless.
