“…but to think soberly, according as God hath dealt to every man the measure of faith.”
Romans‬ ‭12‬:‭3‬

He says:
“But without faith it is impossible to please him: for he that cometh to God must believe that he is, and that he is a rewarder of them that diligently seek him.” Hebrews‬ ‭11‬:‭6‬
God rewards those that diligently seek him, and see how he constructs that statement-
“…he that cometh to God must believe that he is… a rewarder of them that diligently seek him.”
You must believe that when you walk by faith (diligently seek him), you would get results (be rewarded). Faith isn’t wishful thinking and doing things based on your imaginations, your faith must be a response to the word of God, you are thinking, talking and living your life as a response to what you’ve seen in the word.
Something as simple as ensuring not to miss church services simply because you saw in the word that you shouldn’t is living by faith because your action is a response solely to the word.
