Some just use the name, 'Christian’, without understanding what a real Christian is.
Their life styles do not suggest that they are a Christian as often the person lives, acts, thinks, talks, etc. just like a non-Christian.
So what is a Christian really?
Well, a good and succinct answer to that question came in a snail mail letter that I received awhile back from Samaritan's Purse.
Going to their website I was unable to find it posted online so perhaps it is only in printed form.
Not knowing who wrote it, though it might have been Franklin Graham, the President of Samaritan’s Purse, still, it is definitely a must read.
So, without further ado --
