I love St. John, the Apostle. His writings are simple, clear, and to the point. In today's Mass reading from 1 John 4, he makes it clear that
(1) we have not seen God, but if we love one another, God remains in us,
(2) God has given us his Holy Spirit so that we know that we remain in him and he in us,
(3) God is love and this love is brought to perfection among us who remain in him,
(4) love and fear are mutually exclusive. One who fears is not yet perfect in love.
St. John here gives us much food for thought. To those who are still afraid of the physical death, let me say that nothing can match the power of God's love. Let this love fill you to leave no room for any fear.
