How do we know Christ is enough for us?

The realization of our need for Christ stems from being aware of our own sinfulness and the sovereignty of God. Just as only those who were bitten by the serpent looked to the brazen serpent for healing, only those who see their desperate condition will look to Christ. Our acknowledgment of Him as our sufficient Savior indicates that we have been graciously shown our need. In Hebrews 13, the reinforcement of Christ's promise to never leave us highlights His sufficiency in meeting our deepest spiritual needs.
