Faith is a substance not seen. But once you have experienced it and know that God stands behind you through thick and thin. You are well on your way(to knowing what faith is). Our journeys are all very different. All are our very own. This doesn't mean that someone has not experienced the same or similar. It means that there is help and advise along the way. It means that we cannot rely on men alone. We have a physical side of us that gets addressed, because we are social animals. However most have a spiritual side as well. That is where God comes in.
And in the last days it shall be, God declares,
that I will pour out my Spirit on all flesh,
and your sons and your daughters shall prophesy,
and your young men shall see visions,
and your old men shall dream dreams.
