'Order' in the Bible

They went out from us, but they were not really of us; for if they had been of us, they would have remained with us; but they went out, so that it would be shown that they all are not of us.

You know that He appeared in order to take away sins; and in Him there is no sin.

These things I have written to you who believe in the name of the Son of God, so that you may know that you have eternal life.

And we know that the Son of God has come, and has given us understanding so that we may know Him who is true; and we are in Him who is true, in His Son Jesus Christ. This is the true God and eternal life.
