WHY CAN I SAY SO-CALLED CHRISTIAN?
Because we are judged on our latest actions, not on past reputation.
Especially if that reputation was built by others.
There is much which goes by the name Christian, but true Christianity is obedience to the scriptures. It is not about putting on a show.
It is not about mouthing prayers before others.
If our outward conduct is not consistent with the Bible - our rule - then we can legitimately be called so-called Christians.
"...Behold, to obey is better than sacrifice, and to hearken than the fat of rams." (1Samuel 15: 22).
