"A righteous man serves God out of a principle of love. Grace now biases the heart and carries it strongly towards God in ardent affec-
tion. A righteous man serving God is not by constraint but consent. It is heaven to him to serve God! He mounts up in the fiery chariot of love and breathes forth his soul into his Savior's bosom. Love is the 'shibboleth' that differentiates a righteous man from others. The carnal man says, 'What a weariness is it to serve the Lord!,' (Malachi 1:13). The righteous man says, 'What a pleasure is it!' 'I delight in the law of God in the inner man,' (Romans 7:22).
"As the bee delights to suck the flower, so a holy person delights to obey God. He does duty out of love to duty; he prays out of love to prayer. When he sings, he makes melody in his heart to the Lord. Love lines the yoke of religion and makes it easy. As a bride delights in putting on her jewels, as a musician delights in playing on his violin, so a gracious soul delights in obeying God. Love to duty is better than duty; serving God with delight is angelic. The seraphims are described as having wings, (Isaiah 6:2), to show their cheerfulness as well as their ability in God's service."
