“Pursue peace with everyone, and holiness—without it no one will see the Lord“” (Hebrews 12:4, CSB)
The Bible calls Christians to the pursuit of holiness. Holiness is a life long journey that requires intentional action in order to develop. To develop holiness a Christian needs to practice spiritual disciplines that are described in scripture. Spiritual disciplines are both personal and interpersonal.
The biblical spiritual disciplines include scripture study, service in local church, fasting, prayer, and evangelism. This list is not complete but all of these are biblical. Working to develop each one of these disciplines will take time. However, given enough practice each discipline will begin to move the believer to a more Christ like demeanor.
