'Conviction' in the Bible

let us approach [God] with a true and sincere heart in unqualified assurance of faith, having had our hearts sprinkled clean from an evil conscience and our bodies washed with pure water.

But My righteous one [the one justified by faith] shall live by faith [respecting man’s relationship to God and trusting Him];And if he draws back [shrinking in fear], My soul has no delight in him.

Now faith is the assurance (title deed, confirmation) of things hoped for (divinely guaranteed), and the evidence of things not seen [the conviction of their reality—faith comprehends as fact what cannot be experienced by the physical senses].

Remember your leaders [for it was they] who brought you the word of God; and consider the result of their conduct [the outcome of their godly lives], and imitate their faith [their conviction that God exists and is the Creator and Ruler of all things, the Provider of eternal salvation through Christ, and imitate their reliance on God with absolute trust and confidence in His power, wisdom, and goodness].
