Why is man's responsibility important for Christians?

The concept of man's responsibility is essential in understanding the interplay between God's sovereignty and human action. While God sovereignly elects individuals for salvation, Scripture makes clear that each person is held accountable for their choices, particularly in relation to belief in Christ. John 3:19-20 points out that individuals choose darkness over light due to their evil deeds, indicating that condemnation arises from personal rejection of Christ. The balance between divine sovereignty and human responsibility maintains the integrity of God's justice and mercy, highlighting that while salvation is a work of God, people actively choose to believe or reject the offered salvation.
