It seems to me that there is a danger of making faith sound like it's simply assent to biblical doctrines. Of course, if I thoroughly work through the third step with the teachings of Scripture I will avoid this pitfall, but perhaps more emphasis ought to be given that this is something personal - faith in God through Christ. After all, 'this is eternal life, that they know you the only true God, and Jesus Christ whom you have sent' (John 17:3); it is not eternal life to live wholeheartedly according to a system of doctrine per se.
In particular, Calvin insists on the necessity of knowing God as a merciful God, rather than simply knowing something about his will (I take it that by 'knowing God's will' Calvin is talking about something not a million miles from what I've said above).
In trying to avoid the dangers of a vague, woolly mystical approach the equal and opposite danger must also be avoided of reducing faith to simply believing the right things. Real faith is knowing the true and living God, revealed in all his grace in Christ! Anything else will bring spiritual famine and poverty, however good my doctrine is.
