John MacArthur’s most recent post on the Grace To You blog is called ‘Who Is Responsible For Your Spiritual Growth?’

The paradox is found in the believer being both fully responsible, and yet fully dependent on God’s supply. We may not fully comprehend the paradox, but we can exercise faith that it is resolved in the infinite wisdom of God and respond in obedience to His commands.
