The person who has eternal life loves to do the will of God. This is the logical sequence. The man who loves is the man who is anxious to please the object of his love. There is no better test of love that that, and unless you desire to please someone whom you claim to love, I assure you, you do not love that person. Love always wants to be pleasing and to give itself, and anyone who loves God wants to do the will of God.
The one who loves is controlled by this one idea. Having learned what God has done for him and what God is to him, having realized something of this love of God, he says, “Love so amazing, so divine, demands my soul, my life, my all.” Any man, therefore, who has eternal life has this as the supreme object and desire of his life – to do the will of God. – Dr. Martyn Lloyd-Jones
John 14:15 If you love Me, you will keep My commandments.
1 John 5:3 For this is the love of God, that we keep His commandments. And His commandments are not burdensome.
