In the 1960s, love was a central theme among young people. Many songs spoke of love, often the love between a man and a woman, but sometimes love for everyone. Peace and love! Groovy, man! One of the many hits of The Beatles told us that love was all we really need. Although I'm pretty sure they didn't intend it this way, you could say that they were telling us that God is all we need.
The word "love" appears quite often in God's word. In fact, in the NIV, it appears 574 times! The Bible tells us that we should do everything that we do in love (1 Corinthians 16:14). Jesus commanded that we should love one another (John 15:17). Scripture also tells us that love will last forever, along with faith and hope. But of those three things, the greatest is love (1 Corinthians 13:13).
Love was created by God. As children of the living God, as His creation, we are able to love because He loved us first (1 John 4:19). If we love each other, we are born of God and we know God, because love comes from God. God Himself is love (1 John 4:7-8).
So, The Beatles actually did get it right. All we need is love, because love is of God and God is love.
All you need is God!
