Therefore, my beloved, as you 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; for it is God who works in you both to will and to do for His good pleasure." (Philippians 2:12-13)
You can see that the apostle Paul confirms that salvation comes by faith, "work out your own salvation with fear and trembling..." this expresses an aspect of faith, denial, investment and sacrifice (hard work).
Faith is not quick confidence, it's a permanent confidence: lively confidence, wonderful, vigilant. Our salvation is a miracle that God 'works in us' and, that's why it asks for all our attention. Working with 'fear and trembling' is to be conscious that every moment we need to be investing in our encounter with God (like a marriage), at every moment, God is working in us.
Fearing God is, in this way, is loving Him irresistibly!
Denying certain things indicates where our real intention lies, perhaps you can tell me that you've denied several things, but can it be that it was a true surrender? What I mean to say is, was the denial accompanied by fear and trembling?
We have many Christians that have denied their will in front of men and showed that their pleasure was serving our Lord Jesus in front of them, but deep down inside, they hide their true desires and fleshly wills. The devil throws thoughts and each one is kept and fed, they are "supposed" servants, but alone they satisfy those things which they don't do in front of people, they do this inside their four walls, without fear and trembling.
How much do you love God? You want to know? Analyze yourself and see when you're alone, when you're in front of the computer, on your cell phone, inside of your room, in your restroom, with your boyfriend or an unconverted person... your attitude in these positions reveal how much you love the Lord Jesus, and if you've truly been working with fear and trembling.
If you conclude that you love irresistibly, congratulations, you're on the right path towards salvation... now, if you saw that your love for God is not genuine, well, it's time to restore it.
During the next 3 days you will wake up at 3am or 6am to seek the Holy Spirit, you will pour out your soul to Jesus, you'll start working with fear and trembling in your life with God, be in spirit throughout the day, renounce what is hidden or that you still need to surrender, if its necessary confess it to your pastor but don't have that inside you anymore.
Prove to God how much you love Him, renouncing the world, sacrificing your will and seeking Him with intensity. Start first by investing in your interior, that's where the truth about yourself lies... what you are inside reflects in your outward actions.
