How do we know our strength comes from God?

Believers are reminded that their strength is not found in themselves but is solely from the Lord. In Ephesians 6:10, Paul encourages believers to be strong in the Lord and in the power of His might. This acknowledgment of dependence on God highlights a critical theological understanding in Reformed thought—the necessity of grace and divine intervention for living righteously and effectively in the world. As the sermon states, 'By wise counsel thou shalt make thy war,' which indicates that trusting in God's wisdom equips believers for every spiritual battle they face.
