WHAT IS FAITH??
"Faith is the confidence that what we hope for will actually happen; it gives us assurance about things we cannot see."
Hebrews 11:1
Two words describes faith: sure and certain. These two qualities need a secure beginning and ending point. The beginning point of faith is believing in God's character - he is who he says. The end point is believing in God's promises - he will do what he says. When we believe that God will fulfill his promises even though we don't see those promises materializing yet, we demonstrate true faith.
William Lane Craig said once that "Faith is trust or commitment to what you think is true. Why a person thinks Christianity is true may differ from individual to individual. For a person, it might be because God speaks to his heart and produces in him a conviction this is true. To another it may be a more hard-headed intellectual exploration of the evidence that leads him to the same conclusion. But neither comes to faith until he makes that act of trust or commitment to what he thinks is true."
And to me that is so true. God and religion is such an abstract concept. God and religion revolves around the concept of Faith. Without it, there is no point in talking about it.
