Philippians 2

After Paul taught concerning the "discension" of Christ, he then testfies -

"That at the name of Jesus every knee should bow, of things in heaven, and things in earth, and things under the earth;
11 And that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father."  (New Testament | Philippians 2:10 - 11)

Even so, it is Paul's pleadings to these saints that touched my mind this morning -

"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.
14 Do all things without murmurings and disputings:
15 That ye may be blameless and harmless, the sons of God, without rebuke, in the midst of a crooked and perverse nation, among whom ye shine as lights in the world;
16 Holding forth the word of life..."  (New Testament | Philippians 2:12 - 16)

Paul is teaching that everyone, individually, must work out their own salvation.  This is by obedience to the will our Father in Heaven and the Savior.  That means, in order to work out our own salvation, we must learn His will.  We learn His will through prayer, studying the words of life, following His apostles and prophets, receiving His required ordinances and covenants, and attending Church and partaking of the sacrament.  As we strive to do so, we must be careful to avoid murmurings and contention.
