How do we know our flesh is an enemy in spiritual warfare?

The flesh is frequently identified as an enemy in spiritual warfare due to its innate tendency towards sin and rebellion against God. Romans 7:18 states, 'For I know that in me (that is, in my flesh) dwelleth no good thing.' This illustrates the corruption inherent in our fallen nature, which constantly opposes the will of God and the leading of the Holy Spirit.

The Apostle Paul describes the struggle against sin as a war that takes place within believers, stating that the flesh lusts against the Spirit, and the Spirit against the flesh (Galatians 5:17). This underscores the reality of the internal conflict we experience as we seek to live according to God’s will. Understanding this aspect of our spiritual warfare helps us recognize our dependence on Christ and the necessity of His grace to overcome our flesh.
