Timeless truths from Philippians 2:12-13.
We are saved by grace and kept by grace. At the very moment of your salvation, God began a “good work” in you, Phil 1:6. We are to join God in that work. It is an “inside out” job. In other words, God changes your heart! Since everything flows from your heart, everything is impacted. But the mind, will, and emotions take a lot of time and work to change. That is why Paul writes, “work out your salvation with fear and trembling…” You are to work out what has been worked in. You don’t work for your salvation; you work from your salvation. Our attitude in this work is to be reverent. We are to be serious about it.
We join God in this work. “For it is God who is at work in you…” You do not work alone! If you did, you would get nothing accomplished. We are to actively participate with God by disciplining ourselves, yielding ourselves, and humbling ourselves. Our goal is to join the Lord, who does this work according to “His good pleasure.” That means we may not understand, but we know the ultimate end is “His good pleasure.”
“So then, my beloved, just as you have always obeyed, not as in my presence only, but now much more in my absence, work out your salvation with fear and trembling; for it is God who is at work in you, both to will and to work for His good pleasure.” Philippians 2:12-13 NASB
