To be a saint does not mean the absence of wrong or sin. To be a saint in the Bible means to have the Spirit of Jesus living within you. To be a saint in the Bible means to consecrate yourself to God by fighting sin and living the new life. Not a single one of the saints on this earth are perfect, but we make it our goal to strive for this anyway. Sinners who are saints that's what we are dealing with today as we look at the doctrine of sanctification.
Sanctification is the word used to describe the process of kicking the habit of sin.
It is the word used to describe how a person becomes more and more holy, more and more Christ-like. Sanctification is the work of the Holy Spirit within us once we have accepted God's acceptance of us because of Christ Jesus. Sin has two effects on every person's life. It's first effect is guilt. We are all guilty in God's eyes and worthy of hell and eternal damnation because of the sin we are born with as well as the sin we actually commit.
