What does Paul mean by 'being strong in the Lord'?

'Being strong in the Lord' is a directive found in Ephesians 6:10, calling believers to draw strength not from their own abilities but from the Lord. This strength is essential for engaging in spiritual warfare, as believers face real struggles against spiritual forces. Trusting in God's might involves a deep reliance on His Word, the comfort of the Gospel, and the power of prayer, which enhance our resilience and effectiveness in combating spiritual attacks. In a world filled with uncertainty and fear, being strong in the Lord encourages believers to remain steadfast, knowing that God equips and supports them through His Spirit.
