Sanctification is not a passive process. It is a war—a battle against sin, the flesh, and the world. In an era where compromise is celebrated, the believer’s call to holiness is more urgent than ever. While justification is God’s sovereign act of declaring a sinner righteous, sanctification is the lifelong process of becoming conformed to Christ’s image. It is both a divine work and a personal pursuit, a reality accomplished by the Spirit, but requires diligent effort from the believer.
