“Wherefore, my beloved, as ye have always obeyed, not as in my presence only, but now much more in my absence, work out your own salvation with fear and trembling.”
King James Version (KJV)
2:12 Wherefore - Having proposed Christ's example, he exhorts them to secure the salvation which Christ has purchased. As ye have always - Hitherto. Obeyed - Both God, and me his minister. Now in my absence - When ye have not me to instruct, assist, and direct you. Work out your own salvation - Herein let every man aim at his own things. With fear and trembling - With the utmost care and diligence.
Php 2:12 Wherefore, my beloved. From the contemplation of Christ's glory, the apostle turns to the lessons needed by the Philippian church. Work out your own salvation. While Christ is our Savior, and the author of our salvation, we must accept him and work together with him. Hence the Holy Spirit says, "Save yourselves" (Ac 2:40) and "work out your own salvation". Unless we do our part Christ cannot save us. With fear and trembling. With constant anxiety not to fail.
