What does it mean to guard the good deposit?

In 2 Timothy 1:14, Paul instructs Timothy to guard the good deposit through the Holy Spirit, emphasizing the responsibility of every believer to protect and cherish the truths of Scripture. This 'good deposit' refers to the Gospel and sound teaching that Paul imparted to Timothy. Guarding it means actively engaging with Scripture, ensuring that it is accurately represented and taught within the church community. This involves diligent study, faithful preaching, and living out its truths, as the church's integrity and the health of believers depend on the preservation of these sacred truths.
