Why is it important for Christians to rely on Christ as the author and finisher of their faith?

It is crucial for Christians to rely on Christ as the author and finisher of their faith because it underscores the complete work that He accomplished on the cross. Philippians 1:6 assures us that He who began a good work in you will carry it on to completion until the day of Christ Jesus. The sermon elaborates on how our endurance is not founded on our faithfulness, but on Christ's faithfulness to His promise. By looking to Jesus, who endured the cross and despised its shame, we find the strength and assurance needed to continue in our faith. In our journey, we face struggles and temptations, but focusing on Christ's completed work and His ongoing intercession motivates us to persevere.
