Christianity might be called a religion, but it is more of a RELATIONSHIP.
If you don't walk with God, then it becomes more of a religion.
He came for His sheep.
And He spoke of other sheep, not of the Jewish fold.
Joh 10:15 As the Father knoweth me, even so know I the Father: and I lay down my life for the sheep.
Joh 10:16 And other sheep I have, which are not of this fold: them also I must bring, and they shall hear my voice; and there shall be one fold, and one shepherd.
I find it interesting the Muslim religion is VERY similar to the Jewish old testament times, as though they got many of their ways and laws from the old testament.
