How do we know that we can love God?

According to Scripture, our capacity to love God stems from His prior love for us. In 1 John 4:19, it is explicitly stated, 'We love Him because He first loved us.' This indicates that our love for God is a response to His initiating grace. Before we can express love, God must first work in our hearts, which aligns with the doctrine of regeneration. Ephesians 2 elucidates our state of being dead in trespasses, affirming that spiritual regeneration by the Holy Spirit is required for anyone to truly love God. Thus, our love is a gift from God, made possible through His sovereign grace.
