Why is it important to acknowledge our sin before God?

In the context of Numbers 21, the Israelites recognized their sin and approached Moses for intercession. This act of confession is vital because it opens the way for God's prescribed remedy. Recognizing our transgressions leads us to seek out God's grace in Christ. The people’s acknowledgment of their sin demonstrates a humble recognition of their need for divine intervention. Without this acknowledgment, the promise of healing through looking to the brass serpent would have gone unclaimed, exemplifying how we, too, must come before God acknowledging our need for His grace in Christ.
