How do we know that Christ's heart is fixed?

The psalmist declares in verse 1, 'Oh God, my heart is fixed,' which reflects the steadfast nature of Christ. As believers, we see the ultimate expression of a fixed heart in Jesus, who set His face like flint to fulfill His mission of redemption. While our hearts tend to waver, Christ's heart remains firm and focused, perfectly embodying resolve and loyalty to God’s will. His example encourages us to strive for a determined heart, relying on His grace to fix our hearts on Him as we pursue holiness and worship.
