I would appreciate your opinion on Luke 17: 3,4 now.
Begin in chapter 16 for the context. Jesus is teaching on money and covetousness and there were Pharisees who were spying in on the discussion as always. They began to ridicule him. So he went about by the Holy Spirit to tell them they are an abomination to God. He explained that the time of the law and the prophets ruling was over now that the kingdom is preached with him being king. He put them in there place.
Henceforth why he told the story about the rich man and Lazarus at this time. Notice the story is basically about a rich Pharisee who looks with contempt upon the poor as he himself trusts in his riches. Mistaking gain for godliness. Which was commonplace in the era. Even the disciples all marveled when Jesus said rich men ain't gonna make it without Gods help. Within this story you see the correlation between the law and the prophets and the king of the kingdom when he says, 'they have Moses and the Prophets let him here them', Of course after the rich man is in Hell he knew that he himself listened not to them so he asks that Abraham send Lazarus. "They will not believe even if one is sent from the dead" who is Christ our King. Jesus is always the same, he resists the proud and gives grace unto the humble. This story is to tell the Pharisees they won't repent even after his Resurrection from the dead.
Then he turned to his disciples and said...Sin will happen. But be careful to see what is being said here. He is saying some will be forgiven and some will not. Pharisees no forgiveness. But unto them "take heed unto yourselves" or paraphrased "make sure your not one of them by doing what I say next".
See this clearly: If thy brother trespass against thee, rebuke him; and if he repent, forgive him. And if he trespass against thee seven times in a day, and seven times in a day turn again to thee, saying, I repent; thou shalt forgive him.
Your brother has trespassed against you. For HIS sake that trespassed rebuke him. Since this is a face to face encounter, repentance is required for reconciliation between the two. There can be no reconciliation between two if both aren't agreed when both are enlightened as to the problem. Confession must be made.
As you can see, the next thing the disciples ask for is more 'faith' which allows them to do the 'works of faith' such as forgiving a constantly erring brother. Finally he finishes the thought by showing them that when they actually fulfill the role as servants that they are they should humbly admit that turning their brother to repentance and converting him back to a right relationship with them and God was merely there duty to do and they are unprofitable servants.
If a brother sins against us should we forgive him if he is unrepentant, and if not/so why?
I believe this was answered in the exegesis of the text above. If you need more clarity go to Matthew 18 and see why you must forgive everyone their trespasses or not be forgiven by the Father.
What love our marvelous Lord has bestowed upon us that we might bestow it upon others! Praise, Honor and Glory to the Lamb!!!
