You know, if Christianity were just about believing something you have seen or been told or read - I do not think that I could have continued living the life.
I would have still taken that step to faith at Easter 1973 but I could not have done what some friends have done - believed and, pretty much, nothing more.
Without the actual reality of faith, answered prayer, experiencing the presence of God and, furthermore, sharing the experiences of close Christian friends - where would I have been today?
You say you are a Christian - don't just believe it but LIVE THE LIFE as God has set it out for you.
