Why is it important for Christians to build their faith on Jesus alone?

In 1 Corinthians 3:11, Paul emphasizes that Jesus Christ is the only foundation that can be laid for spiritual growth. Any attempt to build upon other foundations—whether personal righteousness, religious traditions, or moral achievements—will ultimately fail and lead to spiritual ruin. As stated in Matthew 7:24-27, those who hear Christ's words and act on them build their lives on rock, able to withstand the storms of judgment. This is vital for believers, as our salvation hinges on recognizing Christ's sufficiency, His completed work, and finding our identity and security in Him alone.
