The Nature of Faith

Hebrews 11.6 without faith it is impossible to please God.

Hebrews 11.1-3 Now faith is the substance of things hoped for, the evidence of things not seen. For by it the elders obtained a good testimony. By faith we understand that the worlds were framed by the word of God, so that the things which are seen were not made of things which are visible.

Amplified version 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]. For by this [kind of] faith the men of old gained [divine] approval. By faith [that is, with an inherent trust and enduring confidence in the power, wisdom and goodness of God] we understand that the worlds (universe, ages) were framed and created [formed, put in order, and equipped for their intended purpose] by the word of God, so that what is seen was not made out of things which are visible.
