We love because he first loved us. Whoever claims to love God yet hates a brother or a sister is a liar. For whoever does not love their brother or sister, whom they have seen, cannot love God, whom they have not see. And he has given us this command: Anyone who loves God must also love their brother and sister.-1 John 4:19-21
What is John telling us here? He is telling us the same thing that Paul told us in 1 Corinthians 13? Of course John is telling us the same thing as Paul. Both Paul and John argued that love is more important then anything else. Why? To answer that question we need to look at the words of John earlier in this section of 1 John.
Dear friends, let us love one another, for love comes from God. Everyone who loves has been born of God and knows God. Whoever does not love does not know God, because God is love. This is how God showed his love among us: He sent one and only Son into the world that we might live through him. This is love: not that we loved God, but that he loved us and sent his Son as an atoning sacrifice for our sins. Dear friends, since God so loved us, we also ought to love one another. No one has ever seen God, but if we love one another, God lives in us and his love is made complete in us.-1 John 4:7-12 NIV
Let’s return to our question of why love is more important than anything else. We are now able to answer that question, with this: love is more important than anything else because God loved us enough, even though we did not love him, to send his Son to die for our sins. That is why we are called to love one another and not hate one another. Remember this God loved you enough to send his Son to die for your sins, and what better way to repay that love and show the world that love then by loving one another. If you truly want to make a difference in the world, put aside your petty differences and stand united in the love that we have been shown by God who first loved us.
