By faith we understand that the entire universe was formed at God’s command, that what we now see did not come from anything that can be seen.
It was by faith that Abel brought a more acceptable offering to God than Cain did. Abel’s offering gave evidence that he was a righteous man, and God showed his approval of his gifts. Although Abel is long dead, he still speaks to us by his example of faith.
It was by faith that Enoch was taken up to heaven without dying—“he disappeared, because God took him.” For before he was taken up, he was known as a person who pleased God. And it is impossible to please God without faith. Anyone who wants to come to him must believe that God exists and that he rewards those who sincerely seek him.
It was by faith that Noah built a large boat to save his family from the flood. He obeyed God, who warned him about things that had never happened before. By his faith Noah condemned the rest of the world, and he received the righteousness that comes by faith.” Hebrews 11:1-7, New Living Translation
If I build a house, I’m not going to start framing the walls and setting sheet-rock and putting a roof on that house until I have solid, firm foundation set in place and I am certain and have full assurance that the foundation is solid and stable.
NASCAR is the biggest spectator sport in America (I think in the world). They know who they can race. The guys that will hold their line and not wreck them and they will run laps side-by-side because they have a foundation of trust with each other.
Faith is not wishful thinking, wishing something to be true when there is no evidence or support for it. Faith is certainty of what is real. Assurance of what I have believed in. Reality and truth as strong as a foundation with trust that will go along with its truth.
