What does the Bible say about the love of God in our hearts?

The Bible emphasizes that the love of God comes from the Holy Spirit and is a fruit of being born again. In Romans 5:5, we see that this love has been poured out into the hearts of believers, signifying an abundant and divine affection that does not originate from human effort. It is not a natural love we can muster up; rather, it is a supernatural love worked in us by God Himself. This love is essential for every believer and is characterized by its selflessness, as it mirrors Christ’s love for us, culminating in the sacrificial act of His death on the cross. As this love abounds in our hearts, it compels us to love others, fulfilling the command of Christ to love one another, as we are called to reflect His love to a watching world.
