What is the foundation of the Christian faith according to the sermon?

In the sermon, the foundation of the Christian faith is emphasized as Jesus Christ, the cornerstone chosen by God for the salvation of His people. Paul states in 1 Corinthians 3:11 that no other foundation can be laid than that which is laid, which is Jesus Christ. This sets the standard for all preaching and teaching in the church. Ministers are called to build upon this foundation through sound doctrine, imparting the truths of Scripture rather than human opinions. The reliance on this foundation ensures that believers are spiritually nourished and that their faith rests on the unshakeable rock of Christ rather than shifting sands of worldly wisdom or experiences.
