What is sanctification according to Les?
Sanctification is the scriptural term for the Christian experience and growth aspect that follows salvation; it is a process, not an event. It covers time, as believers begin as new babes in Christ and mature gradually, not suddenly, over varying lengths of time.
Les explains that salvation is an event, while the Christian life is a process. Once salvation takes place, the Christian experience—sanctification, the word Scripture uses—is the growth aspect that unfolds over time. Believers do not instantly become mature; they begin as new babes in Christ after the new birth, and growth covers time, with some taking much longer than others. He also notes that this new birth cannot happen until a person recognizes their need, as illustrated by Jesus' statement that the sick, not the well, need a physician.
