Faith is being sure of what we hope for and certain of what we do not see. … By faith we understand that the universe was formed at God’s command, so that what is seen was not made out of what was visible.
Keep your lives free from the love of money and be content with what you have, because God has said, “Never will I leave you; never will I forsake you.” So we say with confidence, “The Lord is my helper; I will not be afraid. What can man do to me?”
Now faith is being sure of what we hope for and certain of what we do not see.
