Now faith is being sure of what we hope for and certain of what we do not see. This is what the ancients were commended for. By faith we understand the universe was formed by God's command, so that what is seen was not made out of what was visible.
What door He opens, no one can shuts and what door He shuts, no one can open. I know your deeds. See, I have placed before you an open door that no one can shut. I know that you have little strength, yet you have kept my word and have not denied my name.
Revelations 3: 7-8
