Not to abide in Jesusโ love would mean that we stop believing that we are loved by Jesus. We look at our circumstances - perhaps persecution or disease or abandonment - and we conclude that we are not loved by Jesus anymore. Thatโs the opposite of abiding in the love of Jesus. So abiding in his love means continuing to believe, moment by moment, that we are loved.
John PiperThe purpose of the Lord's Supper is to receive from Christ the nourishment and strength and hope and joy that come from feasting our souls on all that He purchased for us on the cross, especially His own fellowship.
