Genuine love will always compel action. There is no such thing as stagnant, vibrant love. For love to remain kindled hot and strong, it must actively honor its object. I cannot love Christ and live in contradiction to His commands. I cannot love other people and be indifferent towards them. The test of authenticity for love is to look at the sacrifices it compels.
John 15:13 Greater love has no one than this, that one lay down his life for his friends.
1 John 4:9 By this the love of God was manifested, that God has sent His only begotten Son into the world so that we might live through Him.
1 John 5:3 For this is the love of God, that we keep His commandments; and His commandments are not burdensone.
