The end of the Deluge. God has just wiped out all of humanity with a huge flood save for Noah and his family. After the flood ends, God makes a promise to never unleash such destruction again. To symbolize that promise, God creates the first rainbow.
The almost-sacrifice of Isaac. God had promised Abraham a son. Then, out of the blue, God demands that he sacrifice that son. But just when Abraham is about to do it, God stops him, saying it was a Secret Test of Character, and provides a ram to sacrifice instead.
Genesis 23. Abraham's wife, Sarah has died. Abraham asks the people of the land they've been living in for years, the Hittites, if he can buy some land to bury his wife in. The Hittites as a whole tell him, paraphrased, "You're basically a prince among us. You can have whatever land you want, free of charge." And Abraham insists on paying for the land.
Jacob and Esau's reunion. Jacob had fled from Esau because the latter hated him for stealing his blessing. Many years later, Jacob returns to Canaan. When he hears Esau is coming to meet him, Jacob is terrified. His fear turns out to be unjustified, as Esau greets his brother with open arms.
Similarly, there's the reunion between Jacob's son Joseph and his brothers. Joseph's brothers had sold him into slavery in Egypt. Through a series of events, Joseph rises to a position of power and helps Egypt prepare for a famine. When thea famine strikes both Egypt and Canaan, Jacob sends his sons to Egypt, where Joseph has helped store food. When Joseph and his brothers first meet, they don't recognize him. When they realize who he is, they are afraid he might use his position of power to get revenge on them for selling him into slavery. Joseph, however, assures them he has forgiven them, saying that what they intended for bad, God had used for good.
Judah, pleading for Benjamin, and offering himself in Benjamin's place. He knew what Benjamin meant to Jacob, and he himself had been through double the sorrow he and the others had put Jacob through. He knew that if anything happened to Benjamin Jacob might never recover.
What makes this better is that Judah was originally the one who suggested that they sell Joseph into slavery in the first place. And now he's pleading to take Benjamin's place. It shows he truly has changed.
And then there's the reason Joseph was trying to get Benjamin away from the others in the first place: Benjamin was Joseph's full brother, and he was afraid the others would treat Benjamin as badly as they had him. Really, just all of the Joseph story.
Jeremiah 30-33. Most of the book of Jeremiah is concerned with the apostasy of the Hebrews and the consequent judgment from God. Chapters 30-33, on the other hand, foretell the future restoration of Israel. To illustrate his point, Jeremiah buys a field from his cousin while the Chaldeans are besieging Jerusalem. The passages are often understood to have a triple meaning-the return of the Jews to the region of the old kingdom of Judah in 538 BC, the founding of the present-day State of Israel in 1948, and the final reconciliation of Israel to God in the last days.
In the Book of Jonah, God sends Jonah to Nineveh to foretell their destruction due to their living in sin. When the king hears this news, he immediately repents as do the rest of the citizens who put on sackcloths as a sign of their sorriness. God, seeing their Heel-Face Turn, decides to spare the city but Jonah is angry and adamant that the city be destroyed. While taking shelter from the heat under a tree, God sends a worm to kill, which depresses him. God then delivers this line to a sulking Jonah: "You cared about a tree which grew overnight and died overnight, and which you did not work to grow. And should I not care about Nineveh, which has thousands of people who do not yet know their right from their left, and also much cattle!" Here the story shifts away from the Old Testament image of a destructive, vengeful God and foretells the image of the patient, forgiving, loving God of the New Testament. Its quite touching in that God shows compassion towards a people other than the Israelites along with the animals in the city. The book is also one of the few books in the Bible that doesn't have anyone die.
David and Jonathan, anyone?
The end of the Book of Job. The title character has suffered a truckload of disasters. His "friends" tell him it's punishment for some sin he committed. Much argument ensues. At the end, God rebukes Job's friends for the way they spoke to him. Job, however, brings an offering on their behalf and God forgives them.
To boot, Job himself is generously rewarded for keeping his faith, getting back everything he has lost and more, and living on 140 more years.
Elijah saving the widow's son.
Elijah is on the receiving end of one when God shows up, not in anything spectacular or amazing, but in a still, small voice, to tell him "You Are Not Alone".
Read the Song of Songs sometime. It's quite possibly the most wonderful and heartwarming love poetry in existence; prose, but not purple, stirring but not cliched. And, somehow, reading it is like intruding on something private and sacred...
Pretty much the entire Book of Ruth, implications of Les Yay aside, it features three truly kind people, and they all get a happy end.
"Entreat me not to leave thee, or to return from following after thee: for whither thou goest, I will go; and where thou lodgest, I will lodge: thy people shall be my people, and thy God my God: where thou diest, will I die, and there will I be buried: the LORD do so to me, and more also, if aught but death part thee and me."
"Jesus wept" and the resurrection of Lazarus.
In the Greek it's stronger; basically Jesus is freaking mad at what sin and Satan has done to his world and the people he loves. The Greek makes it clear that not only were there tears but Jesus was moaning in grief, the death of Lazarus had wounded his spirit. The act of resurrecting Lazarus is a preview of what he'll finish on the Cross, where death will have no more claim over the people Jesus loves anymore.
The resurrection of Jairus' daughter.
The fate of the "good criminal". He was was crucified next to Jesus, and rebuked a fellow criminal who yelled at Jesus to take all three off their crosses. Jesus then promised the "good criminal" a life in heaven.
Jesus' saving of the alleged adulteress, and his Sermon on the Mount. Not only that, but when he was on the Cross, he pleaded with God to forgive his murderers. That's pretty forgiving.
"Woman, behold your son. Son, behold your mother."
"Greater love has no one than this: to lay down oneís life for oneís friends. You are my friends if you do what I command. I no longer call you servants, because a servant does not know his masterís business. Instead, I have called you friends, for everything that I learned from my Father I have made known to you." - John 15:13-15
The entire purpose of Jesus on Earth. God was willing to sacrifice and forsake his OWN son (who willingly did so with determination) just so that humanity - who were unworthy of salvation - could be saved.
When Paul's jail house broke around him freeing him from his prison he decided to stay. Seeing that his prison guard was fearful for his life he told him, "Do yourself no harm for we are still here." Overwhelmed by the situation the guard falls to his knees and asks quite plainly, "What must I do to be saved?" The answer given is, "Believe on the Lord Jesus Christ and you shall be saved." On that day Jesus did save that man as he was converted by Paul's words.
The Parable of the Good Samaritan that ends with Jesus asking the lawyer of the three men who passed by the stricken man, who was his neighbor. When the Lawyer responds, "The one who helped him," Jesus simply responds, "Go and do the same."
The Parable of the Lost Sheep.
The Parable of the Prodigal Son.
Even better if you are familiar with what the culture was like back then. When the Son asked his Father to give him his inheritance, he was basically saying "You know what, Dad? You're pretty much dead to me; I don't need you anymore, so just give me my inheritance now so I can do things my own way." Can you imagine what a blow that must have been to the Father, hearing his own Son say things like that to him? And yet after the youth wastes his money on an unhealthy lifestyle, he realizes what a mistake he's made and decides that he wants to return to his Father again, if so only as a servant. But when the Father sees that his son is returning- just a glimpse, that was all he needed- he didn't walk, but ran toward his son, embracing him with open arms, throwing a party in his honor and completely forgiving him for all the things he's done. That's God-given grace personified.
