What does the Bible say about love in relation to our duty to God?

The Scriptures emphasize that our reasonable service to the Lord is fundamentally about love. In 1 John 4:16-21, we learn that we have known and believed the love that God has for us, and because He first loved us, we are compelled to love Him and our brothers. Love is the central theme of the believer's conduct towards God, the church, and others, urging us to fulfill all the law by loving our neighbors as ourselves (Galatians 5:13-14). Understanding and embodying this love is essential for our spiritual lives and witness in the world.
