"The test of the genuineness of our love for God's family lies in this question - do we love God himself and do we obey his commands? For loving God means obeying his commands, and these commands of his are not burdensome, for God's 'heredity' within us will always conquer the world outside us." 1 John 5:2-4
I'm sure you've noticed this before, but it seems to me that we tend to have a negative, uncomprehending view of "obedience" - negative, because we think of it as legalistic, and uncomprehending, because we understand obedience only in the context of the Old Covenant, not the New. Let me make it as simple as possible, and echoing of John.
Under the Old Covenant, the entirety of the message from God to His people was, "You must obey," and they failed at every turn.
Under the New Covenant, and because of the glorious work of Jesus, both by His life and His now living inside us, the new message is, "Now you can obey."
Philippians 2:13 - "For it is God who is at work within you, giving you the will and the power to achieve his purpose." Like John said, "God's 'heredity' within us will always conquer the world outside us" - the work of obedience, under this New Covenant, is Jesus' work. Our work is to set our will on His... and surrender.
