What does the Bible say about holding fast to the faithful word?

Holding fast to the faithful word means gripping the message of the gospel so tightly that it cannot be taken away. This faithful word is the means by which faith is born and sustained, as emphasized in Romans 10:17, which declares that faith comes by hearing the word of God. The faithful word is not just any scripture; it specifically pertains to the gospel message that reveals Christ and God's salvific plan for His elect. It is crucial for believers, especially pastors, to hold on to this gospel in both teaching and practice, as it is central to the faith and the church's mission.
