He who has My commandments and keeps them is the one who loves Me; and he who loves Me will be loved by My Father, and I will love him and will disclose Myself to him.
~ Jesus
This is My commandment, that you love one another, just as I have loved you.
~ Jesus
So, we show our love for Jesus by our love for one another.
We love our brother (who we can see) to demonstrate our love for God (who we cannot see).
Consider these words penned by John, one of Jesus apprentices:
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.
+++ Lord, lead me in the way of love today. Help me to see and recognize the opportunities you give me to love those around me, and in so doing, love You. And help me to love like you, laying aside my rights and privileges for the sake of others, even if it hurts me. +++
