How do we know that Christ is our only source of strength?

Throughout Scripture, Christ is depicted as the source of our strength and sustenance. In 2 Kings 4, the widow's dependence on Elijah, a picture of Christ, reveals how believers rely on the Lord for help in times of need. The passage reminds us that even in our weakness, God's strength is made perfect. Our struggles are often designed to lead us to Him, demonstrating that we are not self-sufficient. Philippians 4:19 echoes this truth, as Paul assures that God will supply all our needs according to His riches in glory by Christ Jesus.
