The trustworthy saying in Titus 3 refers to the gospel of salvation through God's mercy and the work of the Holy Spirit.
The 'trustworthy saying' in Titus 3 encapsulates the core of the Christian message — that salvation is a work of God's mercy, not our righteousness. Paul invites Titus to insist on preaching this truth, which emphasizes the complete reliance on God's grace through the washing of regeneration and renewal by the Holy Spirit. This saying reminds believers that entrance into the community of faith is not earned but is a gift freely given by God. By emphasizing this dependable truth, Paul underscores the importance of grounding our understanding of salvation in the gospel, which in turn encourages believers to live in a manner consistent with their divine calling — to engage in good works.
