What does it mean to build on the foundation of Christ?

To build on the foundation of Christ means to acknowledge one's lost and sinful state, understanding that without Christ, there is no hope for salvation. As the sermon explains, one must dig deep into their own heart to recognize their wickedness and shortcomings. Upon this realization, a believer then turns to Jesus as the perfect Savior, fully capable and willing to save. This act of faith is likened to committing oneself to the foundation stone, allowing Christ to be the center of one's life. Properly built upon this foundation ensures that when trials come, believers remain secure and steadfast, as they are grounded in the truth of Scripture.
