1 John 4 tells us that our Love for one another is a sign that God abides within us. Anyone who does not Love does not know God.
God is Love. Love is from God, and whoever Loves those around him has been born of God and knows God. The Love of God was made manifest among us when God sent his only Son into the world for our salvation and everlasting life.
It was not a one-way Love. In sending His Son, God showed us that He Loved us. He sent His Son to be the propitiation for our sins. Therefore, if God Loved us, we should also Love one another!
No one has ever seen God. Yet, when we Love one another, God abides within us and His Love is perfected in us!
Through our Love, we know that we abide in Him and He in us, because He has given us His Holy Spirit. His Spirit is Love.
Our Love testifies that the Father has sent His Son to be the Savior of the world. And whoever confesses that Jesus is the Son of God accepts God to abide within. He who abides in Love abides in God and God abides in him.
We are perfecting Love within us by accepting Jesus as the Son of God, receiving the Holy Spirit, and abiding in Love. In perfect Love, we may have confidence at the day of Judgement, because God is Love. John said, "As He is, so also are we in this world".
There is no fear in Love. Perfect Love casts out fear. Fear is a part of punishment, and whoever fears has not been perfected in Love. We Loved because He first Loved us!
If anyone says that he Loves God and is filled with hatred, then he is a liar. He who does not Love his brother who is right before his eyes cannot Love God who he has not seen.
This is the commandment we have from God: whoever Loves God must also Love his brother.
As Christians, we should ask ourselves: Are we filled with the Holy Spirit, or are we filled with hatred which comes from the evil spirit? Do we love our neighbor greater than we love ourselves? Do we claim to be filled with the Holy Spirit while making harsh comments of hatred to our brother? Does our outward expressions expose the liar within our hearts?
