God's plan of salvation is meant to produce holiness in believers. Salvation rescues people from sin, its guilt, power, and eventual presence. While salvation provides forgiveness, it also places believers in union with Christ to be transformed into his moral likeness through the Holy Spirit. The purpose of salvation is because of human sin, which is any lack of conformity to God's law and rebellion against him. God saves people so they can be increasingly conformed to Christ's righteousness, love, humility, and other virtues. Ultimately, God is in the business of holiness - he disciplines believers so they can grow into full Christ-likeness.
