To sum up, YES, this "rule" IS Biblical, and SHOULD be followed by all Christians.
bob>It's not a rule, it's a cliche and all cliche's are wrong. Let's take "love the sinner" when the sinner comes into your house to kill your wife/kids, you love the sinner? You hate the sin alright, but the sin is not the product of itself, it's the evil done by the sinner, if you hate the sin/murder, then you have to hate the sinner/murderer, without him there is no sin. Also, how does one separate the sin from the sinner? It is even possible to do that? God doesn't do that, God washes away the sin leaving the sinner clean.
We ARE supposed to "hate evil" or "hate sin", but YET we are ALSO supposed to "love" ALL "sinners"
bob>You love the sinner that killed your wife/kids?
, including ourselves, since NONE of us are "perfect". When we only point out the "sin" in others, and ignore our own, we USURP God's place of judgment, which is NOT something we should be doing, and God will use OUR "measure" of judgment against US.
bob>We are to rebuke sinners especially if they are Christians, right?
23 Jesus answered and said unto him, If a man love me, he will keep my words: and my Father will love him, and we will come unto him, and make our abode with him.
24 He that loveth me not keepeth not my sayings: and the word which ye hear is not mine, but the Father's which sent me.
4 And I prayed unto the LORD my God, and made my confession, and said, O Lord, the great and dreadful God, keeping the covenant and mercy to them that love him, and to them that keep his commandments;
5 And said, I beseech thee, O LORD God of heaven, the great and terrible God, that keepeth covenant and mercy for them that love him and observe his commandments:
20 The LORD preserveth all them that love him: but all the wicked will he destroy.

IJohn 2:3-4"We know that we have come to know him if we obey his commands. The man who says, "I know him, but does not do what he commands is a liar, and the truth is not in him."
