a more sure word of Prophecy

Philippians 2:5, 12-13 KJV Let this mind be in you, which was also in Christ Jesus: [12] 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. [13] For it is God which worketh in you both to will and to do of his good pleasure.
