So you accept the possibility that there is a God?
I'm agnostic, I see no proof either way, so yes, until disproven with actual facts, a god is a possibility. But so far, I see no actual facts supporting a claim for the existence of a god.
And you will never see any such facts and the reason is God wants you to have faith of His existence.
"Do not be afraid any longer, only believe." ( Mark 5:36)
Faith is one of three things that endure forever - the others being love and hope.
If you understand faith for what it really is - not just believing a set of facts, but an abiding relationship of trust between two parties; you will understand that faith is essential because it is the eternal basis for our relationship with God throughout all eternity.
Faith makes perfect sense, to those who understand.. But understanding comes by faith; not faith by understanding.
