@demotruk, @kyriacos, If you have the time and an inquisitive mind I suggest you read Evidence That Demands a Verdict
"Christianity is either EVERYTHING for mankind, or NOTHING. It is either the highest certainty or the greatest delusion...But if Christianity be EVERYTHING for mankind, it is important for every man to be able to give a good reason for the hope that is in him in regard to the eternal verities of the Christian faith. To accept these verities in an unthinking way, or to receive them simply on authority, is not enough for an intelligent and stable faith".
