What should Christians do when facing adversity according to Habakkuk?

The sermon draws from Habakkuk's reaction amidst the impending invasion of the Chaldeans. Despite the uncertainty and fear expressed in Habakkuk 3:17-19, he resolves to rejoice in the Lord and affirms that God is his strength. This reflects an important principle for Christians: that true joy and strength come not from circumstances but from their relationship with God. In times of adversity, believers can find their assurance in God's promises and His sovereign control over all situations, leading to a posture of worship and confidence rather than despair.
