What is the relationship between faith and love?

[arunangelo]

God is love. Therefore, faith in God is faith in love (which is God’s Spirit). Since true love was revealed in Jesus, who sacrificed His life to free us (who were unfaithful to Him and sinned against Him) from sin; true faith is to believe in this type of love. We would, therefore, be merciful, (Matthew 9:13), compassionate, forgiving (Luke 6:37), humble, gentle, self-controlled, patient, generous, faithful, kind and pure of heart (Galatians 5:24-26). In addition, we would do good acts not because the law requires them, or we are afraid of punishment, or we want to be rewarded; but because we love God.

[crossnote]

And we have known and believed the love that God hath to us. God is love; and he that dwelleth in love dwelleth in God, and God in him. Herein is our love made perfect, that we may have boldness in the day of judgment: because as he is, so are we in this world. There is no fear in love; but perfect love casteth out fear: because fear hath torment. He that feareth is not made perfect in love.
(1Jn 4:16-18)

I think this passage is great to show the interplay of love/faith/fear.

[dga]

We can not receive the love of God, without faith. We receive everything from God, only by faith, even his love. He can love us and wants to give us his love, but we also have a part to play. It is like a good friend, coming to us, and giving us a gift. It is us who have to stretch our hand, and to receive that gift.
It is similar with the love God has for us. We have to receive it by faith, just as we receive our salvation by faith. Love likes to be trusted and accepted by faith. If it is not accepted by faith, it feels rejected - 1 Corinthians 13:7, Galatians 5:6.
