You're right. There's no need to change this at all.
You work OUT your Salvation.
Which means you walk in the Spirit by reading and meditating on the Word. Keep assembling with the Brethren, do good works for Christ and His Kingdom by helping others in all sorts of ways, etc...
Just like you work OUT your physical body by doing exercises to keep fit. You don't work out your physical body to attain it.
It DOES NOT SAY or mean, work FOR your Salvation.
Amen! Notice in
Philippians 2:12 that Paul said to "work out" your salvation and NOT "work for" your salvation. When we "work out" at the gym, we exercise to develop our body that we already have and not to get a body. Farmers "work out" the land, not in order to get the land, but to develop the land they already have. The Greek verb rendered "work out" means "to continually work to bring something to completion or fruition." We do this by actively pursuing the process of ongoing sanctification, which is the result of being set apart for God's work and involves the process of being conformed to the image of Christ.
This conforming to Christ involves the work of the person, but it is still God working in the believer who has already been justified by faith. In verse 13, Paul goes on to say, "for it is God who works in you both to will and to do for His good pleasure." Ongoing or progressive sanctification has no bearing on justification. That is, even if we don't live a sinless, without fault or defect, flawless, absolute perfect life 100% of the time (which we won't) we are still justified by faith in Christ. (
Romans 5:1) Where justification is a legal declaration that is instantaneous, ongoing sanctification is a process.
In regard to "fear and trembling," it pertains to a healthy fear of offending God through disobedience and a righteous awe and respect or reverence for Him. (
Proverbs 1:7;
Psalm 2:11;
Psalm 34:9;
Isaiah 66:2) Prior to my conversion, while still attending the Roman Catholic church several years ago, I basically saw God as a tyrant who couldn't wait to punish me every time I messed up and throw me into hell for not being "good enough." That is an unhealthy fear of bondage and insecurity which is not from above!
Paul uses the same phrase "fear and trembling" in
2 Corinthians 7:15 in which he refers to Titus as being encouraged by the reception of him by the Corinthians "with fear and trembling," that is, with humility and respect for his position as a minister of Jesus Christ. In
1 Corinthians 2:3, we see that Paul himself came to the Corinthian church in "weakness and fear, and with much trembling" in regard to the huge responsibility and critical importance of the work in which he was engaged.
