It is in the mortifying, the slaying of self, that the wonderful powers with which God has fitted you to serve Him, can be set free for a complete surrender to God, and offered to Him to be accepted, and sanctified, and used. And though, as long as you are in the flesh, there is no thought of being able to say that self is dead, yet when the life of Christ is allowed to take full possession, self can be kept in its crucifixion place, and under its sentence of death, that it shall have no dominion over you, not for a single moment. Jesus Christ becomes your second self. (Andrew Murray)
I often hear of the struggles of a saint desiring to serve God, but who falls short of their calling to live a life of devotion and service through the Holy Spirit. Why is this so? The roadblock to walking in the newness of life in Spirit is the self. The self needs to die daily in experience as it has been crucified in the heavens through the work of the Cross. Our current life experience is where we live out what has been accomplished by Christ for us. No longer should we serve the self in our flesh – we have been set free of that obligation – though we are free to choose serve the self in lapses of not allowing the Spirit to have control of us. The new life is available in Christ to serve Him only and not the desires of the flesh for the self – again we are free to choose between the new nature of the Spirit (our new natural inclination which is made easier over time as we learn to surrender to the Spirit) and the old nature of the flesh or the self (which is harder to choose because it is not of our nature, but still within us. Theologians like to comment that we are dual-natured, which is true in experience, but we have one nature in Christ.
The key is to be in Christ by surrendering to the Spirit and killing the self on a daily basis. Pray for a greater understanding of this concept and how to apply it in daily living. God desires to give you all wisdom in how allow the Spirit to reign as the rightful King of your heart.
If any of you lacks wisdom, let him ask of God, who gives to all liberally and without reproach, and it will be given to him. (James 1:5)
As His divine power has given us all things that pertain to life and godliness, through the knowledge of Him who called us by glory and virtue. (2 Peter 1:3)
Therefore I also after I heard of your faith in the Lord Jesus and your love for all the saints, do not cease to give thanks for you, making mention of you in my prayers; that the God of our Lord Jesus Christ, the Father of glory, may give to you the spirit of wisdom and revelation in the knowledge of Him. (Ephesians 1:15-17)
