What does the Bible say about self-denial in Christianity?

In the New Testament, self-denial is a fundamental aspect of true discipleship. Jesus instructs His followers in Luke 9:23 to deny themselves and take up their cross daily, which signifies the sacrifice and commitment required to follow Him. This teaching is echoed throughout Scripture, indicating that true faith is demonstrated through selflessness and a willingness to suffer for the sake of Christ. The call to self-denial challenges the modern tendency towards comfort and luxury, urging believers to reflect on their priorities and lifestyle choices in light of the cross.
