What does the Bible teach about spiritual warfare?

Spiritual warfare is a recurring theme in Scripture, highlighting the ongoing battle between the spirit and the flesh. As expressed in Psalm 60, David laments feeling cast off and recognizes that true strength comes through reliance on God to fight our battles. Ephesians 6:12 reminds us that our struggles are not merely physical but against spiritual forces. This teaches believers that they must rely on God's strength and truth, involving prayer and the Word, to overcome temptation and sin instead of attempting to prevail through their own might.
