Beloved, if God so loved us, we ought also to love one another. No man hath seen God at any time. If we love one another, God dwelleth in us, and his love is perfected in us. 1 John 4:11-12 KJV
Love is the overwhelming force of Faith.
For in Jesus Christ neither circumcision availeth any thing, nor uncircumcision; but faith which worketh by love.
Galatians 5:6 KJV
We, as Christians, must love each other as God loves us. It’s the way the world will know us.
