How can Christians not fulfill the lust of the flesh?

The key to not fulfilling the lust of the flesh is found in the practice of walking in the Spirit. As Galatians 5:16 indicates, this walking is not a temporary measure but a continuous focus on Christ and His righteousness. When believers make this their priority, they experience the power of the Spirit to resist temptation and sin. This does not imply a struggle that is to be undertaken alone; rather, it involves a daily dependence on Christ's finished work and the transformative power of the Spirit in their lives, leading to a life that is increasingly reflective of Christ himself.
