How do we know that self-denial is necessary for Christians?

Self-denial is critical for Christians as Jesus explicitly states in Luke 9:23 that anyone who wishes to follow Him must first deny themselves. This denial reflects a heart intent on putting Christ above all else, illustrating the cost of discipleship. Furthermore, the struggle against our fleshly desires as mentioned in Romans 8:5 emphasizes that true believers will live in a way that pleases the Spirit rather than the flesh. This commitment to self-denial is essential for nurturing a genuine relationship with Christ and reflects an understanding of His suffering and purpose in our lives.
