Christian Freedom - Duty, or Delight?

Do I obey because I desire to be pleasing to the God who has made and redeemed me, or do I obey only because it is some onerous duty?

The freeness of the Christian consists in this, that he obeys the commands of God, not only because God has commanded them, but out of principle of love and delight, and because he has within his heart a nature agreeable to the things commanded. He prays because God commands prayer, but not only so. He prays because there is a suitableness between his heart and the work of prayer, between his soul and the duty. He has desires after God, and his soul delights in his approaches to, and his converse with, God. (pg. 147, The True Bounds of Christian Freedom by Samuel Bolton)
