How do we know God's love is the reason we love Him?

The Apostle John emphasizes that our love for God is a response to His prior love for us, as stated in 1 John 4:19. This foundational love is the work of God's grace in our hearts, transforming us from enemies of God into lovers of God. It is through this divine love that we are enabled to respond in love, fulfilling the relationship outlined in Scripture where loving God naturally leads to obeying His commandments and seeking His presence. Thus, our love is not an independent act but a reflection of His initiating grace.
