What does the Bible say about holding fast to faith?

Hebrews 10:23 instructs believers to 'hold fast the profession of our faith without wavering; for he is faithful that promised.' This emphasizes that our confidence should not be placed in a past act but consistently in God's unwavering faithfulness. The text calls believers to acknowledge and embrace their faith in God Himself, rather than clinging to a profession made long ago. True faith is a continuous recognition of God's promises and His ability to fulfill them, as demonstrated in the lives of biblical figures such as Abraham, who did not waver in belief despite challenging circumstances.
