12 And the Lord sent Nathan to David. He came to him and said to him, “There were two men in a certain city, the one rich and the other poor. 2 The rich man had very many flocks and herds, 3 but the poor man had nothing but one little ewe lamb, which he had bought. And he brought it up, and it grew up with him and with his children. It used to eat of his morsel and drink from his cup and lie in his arms, and it was like a daughter to him. 4 Now there came a traveler to the rich man, and he was unwilling to take one of his own flock or herd to prepare for the guest who had come to him, but he took the poor man’s lamb and prepared it for the man who had come to him.” 5 Then David’s anger was greatly kindled against the man, and he said to Nathan, “As the Lord lives, the man who has done this deserves to die, 6 and he shall restore the lamb fourfold, because he did this thing, and because he had no pity.”
7 Nathan said to David, “You are the man!
5 When Silas and Timothy arrived from Macedonia, Paul was occupied with the word, testifying to the Jews that the Christ was Jesus. 6 And when they opposed and reviled him, he shook out his garments and said to them, “Your blood be on your own heads! I am innocent. From now on I will go to the Gentiles.”
1 Corinthians 5
8 Owe no one anything, except to love each other, for the one who loves another has fulfilled the law. 9 For the commandments, “You shall not commit adultery, You shall not murder, You shall not steal, You shall not covet,” and any other commandment, are summed up in this word: “You shall love your neighbor as yourself.” 10 Love does no wrong to a neighbor; therefore love is the fulfilling of the law.
You sum up the whole New Testament teaching in a single phrase, if you speak of it as the revelation of the Fatherhood of the holy Creator. In the same way you sum up the whole of New Testament religion if you describe it as the knowledge of God as one’s holy Father. If you want to judge how well a person understands Christianity, find out how much he makes of the thought of being God’s child, and having God as his Father. If this is not the thought that prompts and controls his worship and prayers and his whole outlook on life, it means that he does not understand Christianity very well at all.
…For everything that Christ taught, everything that makes the New Testament new, and better than the Old, everything that is distinctively Christian as opposed to merely Jewish, is summed up in the knowledge of the Fatherhood of God. “Father” is the Christian name for God.
JI Packer, Knowing God, emphasis added
Once our eyes have been opened to see the enormity of our offence against God, the injuries which others have done to us appear by comparison extremely trifling. If, on the other hand, we have an exaggerated view of the offences of others, it proves that we have minimized our own.
