How often we hear people say, and even say ourselves, "Oh, I wish I knew the Lord's will" for some decision they need to make, or crisis, or question they're pondering. But in these last two verses, Jesus tells us the Will of God: 1) that He "should not lose anything of what [the Father] has given [Him]" and 2) "that everyone who sees the Son and trusts Him should have eternal life." THE Will of God is to possess and redeem. How stunning!
But did you notice that each of these will-of-God statements is binary, composed of two parts? The first part in each was different, but the second was the same: He will "raise [them] up when the last day comes." The word John uses there for "raise up" means just that - "to raise up" or "raise from the dead" - but it also has a lesser definition that goes beautifully with what we know to be one of the true definitions of our lives-in-Him: "to produce a witness."
THE Will of God is to possess and redeem, that we might be raised up - raised from the dead, in fact - and produced as witnesses of what we know and have seen of Him.
