How do we know that God's love is perfected in us?

The perfection of God's love in us is evidenced by our active love toward others. According to 1 John 4:12-13, the act of loving one another indicates that God dwells within us. This love is not self-generated but comes from God who has poured His Spirit into our hearts. As we grow in our understanding and experience of God’s love, we begin to reflect that love in our interactions with others, indicating that His love has reached its intended fulfillment in us. Perfection here does not mean sinlessness but rather indicates that love’s intended goal is being accomplished in our lives, culminating in a heart that loves unconditionally.
