What does the Bible say about the steadfastness of faith?

In Colossians, Paul expresses joy in the steadfastness of faith among believers, highlighting that true faith must be firmly rooted in Christ, who is the rock of our salvation. Steadfastness indicates a firm grip on the truth, unmarred by the shifting doubts and tribulations we face in life. The power to remain steadfast comes not from ourselves but through the faithful work of the Holy Spirit, who helps keep us from falling, emphasizing that apart from divine grace, we would surely fall away.
