Why is discipline important in the Christian faith?

According to Hebrews 12:1-2, discipline plays a crucial role in the life of a believer. The Scripture calls us to lay aside every weight and the sin that so easily besets us. This requires a daily exercise of faith, where we intentionally remove habits, relationships, or routines that slow us down spiritually. Discipline is not simply about avoiding sin but actively striving against it, as believers engage in the ongoing battle against the flesh. By practicing self-control and making sacrifices, Christians are trained and equipped to run their race with patience, keeping their focus on Jesus, who empowers them through His grace.
