How do we know the doctrine of strength in Christ is true?
Answered in 1 source
The doctrine is supported by scripture, which repeatedly shows God empowering His people in their weaknesses.
The truth of relying on Christ for strength is reinforced throughout biblical history. Old Testament figures like Jacob and Elijah experienced divine strength in their moments of need, demonstrating that God's power is made perfect in human weakness (2 Corinthians 12:9). Isaiah 40:29-31 points out that God gives power to the faint and strengthens the weary, indicating His consistent support for His people across all ages. Through Christ's atoning work and the indwelling of the Holy Spirit, believers now have direct access to this strength, which is evident in the lives of those who trust in Him.
