Philippians 2:12-18
12 Dearest friends, you were always so careful to follow my instructions when I was with you. And now that I am away you must be even more careful to put into action God’s saving work in your lives, obeying God with deep reverence and fear. 13 For God is working in you, giving you the desire to obey him and the power to do what pleases him. 14 In everything you do, stay away from complaining and arguing, 15 so that no one can speak a word of blame against you. You are to live clean, innocent lives as children of God in a dark world full of crooked and perverse people. Let your lives shine brightly before them. 16 Hold tightly to the word of life, so that when Christ returns, I will be proud that I did not lose the race and that my work was not useless. 17 But even if my life is to be poured out like a drink offering to complete the sacrifice of your faithful service (that is, if I am to die for you), I will rejoice, and I want to share my joy with all of you. 18 And you should be happy about this and rejoice with me.

Paul is talking about working out their problems which they had in the church and working out the problems in their own Christian lives. He is not there to help them and is not sure that he ever will be there again because he is in a Roman prison. So he tells them to work out their own salvation. Paul instructs them and us that God works out that which He had worked in. If God has saved you, He has saved you by faith plus nothing. Your spirit is in perfect communion with God.  He will never accept any kind of good works for salvation. But after you are saved, God talks to you about your works. This is the action for your soul, your mind, emotions and will. The salvation that He worked in you by faith is a salvation He will also work through you by your soul. You are saved for good works for the Kingdom of God. God puts the desire in you and your mind thinks His thoughts and you will to do His will and your emotions are surrendered to His. When you stand before Jesus, He will not ask about your sin, it has been covered by His Blood, but He will ask you what did with the gifts He gave you.  Did you surrender your soul to Him? Did you become Christ through your thoughts, will and emotions?

Have a God Day!
