We are called to live Holy Lives because He is Holy. If a Holy God has taken up permanent residence in us, then how can we live unholy. We can in the flesh. We can live unholy lives, and the grace of God will abound more and more. But, if our minds are being renewed by the word and not being conformed to this world but being transformed by that renewing of our minds, then the Holy Spirit that is living in us, that has written God’s Laws on our hearts is not going to allow us to live unholy. The blood of Jesus has taken our sin consciousness, but if we continue to live in a habitual sin, then the Holy Spirit is going to exercise the duties of his office by bringing conviction, not condemnation. Jesus did not come into the world to condemn the world but to save it, so the Holy Spirit is not going to condemn, but He does convict and bring whatever sin may be in your life forward so that you may repent of that sin.
However, we do not live holy lives as a work to salvation, but as a work of salvation. Two very small words make all the difference in the world: “to” and “of”. If we are trying to live a holy life to earn our salvation which would be a work TO salvation, then we are wasting our time. It is not possible. But, if we are living holy lives as a work OF salvation, then it is Christ Jesus that is producing fruit in us because He is the Vine and we are the Branches and together we are rooted in the father.
We must live Holy lives, because we are to be imitators of God. We want to be like Jesus and we want to do the works of Jesus, but we cannot do these things of ourselves, but of He that is in us. Be Holy for I am Holy, that is what the Lord says. We renew our minds and we bring our flesh unto submission not because of works but because of our love for HIM.
If we continue to live in sin, then we risk the chance of becoming reprobate. We risk the chance of our hearts becoming hardened toward God and if the enemy were to slip in and test us, we would fail, because our hearts would have become hardened and our faith diminished. Faith without works is dead but not works to salvation, but works of salvation, because of He that is in us.
