When we are caught up in this Trinitarian community of love it will express itself in how we love one another. As God loved the world and reached out to us to draw us into the fellowship of His community, so the mark that we have this fellowship with God is that we extend it to others. Jesus’ love for us was a lay-down-your-life generous kind of love.
“Beloved, let us love one another, for love is from God; and everyone who loves is born of God and knows God. The one who does not love does not know God, for God is love. By this the love of God was manifested in us, that God has sent His only begotten Son into the world so that we might live through Him. In this is love, not that we loved God, but that He loved us and sent His Son to be the propitiation for our sins. Beloved, if God so loved us, we also ought to love one another. No one has seen God at any time; if we love one another, God abides in us, and His love is perfected in us.” 1 John 4:7-12 (NASB)
