I am the vine, you are the branches. Those who abide in me and I in them bear much fruit, because apart from me you can do nothing. (NRSVCE John 15:5,8)
Someone asked him, “Lord, will only a few people be saved?” He answered them, “Strive to enter through the narrow gate, for many, I tell you, will attempt to enter but will not be strong enough.” Luke 13:27
