Jacob's Gifts

As stated elsewhere, Jacob gives all LOSTIES he visits both a touch (vitality? destiny towards the island?) and a gift. We have yet to see if he visited more Losties. In the finale, we only saw the Losties who were in 1977, leading us to speculate that he was providing himself a chance at rebirth, and the island struggle to continue. Following is what Jacob gave, and conjecture about what it means.

GIFTS | SIGNIFICANCE

MORE SPECULATION
Jacob probably touched others as well. We don't know yet. But he was clearly setting something up.

Did Jacob cause Nadia's death, or did he save Sayid's life? See Sayid's story here.
