(1) John 10:27-29 says “My sheep hear my voice, and I know them, and they follow me. I give them eternal life, and they will never perish, and NO ONE will snatch them out of my hand. My Father, who has given them to me, is greater than all, and no one is able to snatch them out of the Father’s hand.”
The Point: “No one” up above surely means NO ONE. I mean absolutely no one. So … even YOU cannot snatch yourself out of God’s hands.
(2) The second one I got from the Puritan John Owen (1616-83). John Owen basically raised a question of the good King Hezekiah whose story is recorded the Bible. And as the story went, Hezekiah was about to die due to being very ill and so he prayed to God asking God to spare him and God gave him an additional 15 years of life.
~~> So the question becomes, given that God has given Hezekiah a 15 years extension on his life, is Hezekiah now free to do as he pleases?
Does he need to look after his health anymore? Can he eat and drink as he pleases now? Can he now become a drunkard, drinking excessively because it will do no ill to his liver? Can he stop doing all exercise?
