ISB ~ 1 John 4 v8

God is love:God exists as an eternal act of love, with the Father, Son, and Spirit giving themselves to one another in an everlasting embrace. This love of the Trinity, which has its eternal source in the Father, spills over into history through the sacrificial love of the Son (Rom 5:8) and the sanctifying love of the Spirit (Rom 5:5). For John, we can be sure that God lives in us if we love others as God loves—genuinely, sacrificially, unconditionally. In this way, God’s trinitarian love is reflected on earth as it is in heaven (CCC 221). See note on Jn 14:31.
