Everyone have a measure of faith, Christian, or Atheist. They both have atleast some amount of faith. Faith is not the belief in God. Faith is said to be in Hebrews 11:1 "Faith is the confidence that what we hope for will actually happen; it gives us assurance about things we cannot see." NIV
So think about this; have you seen the wind? Do you think the next time you sit down, the chair will support you? How about if there is a next breath? Life IS impossible without faith. No matter what religion you come from.
