And you will seek Me and find Me, when you search for Me with all your heart.
-Jeremiah 29:13


The problem of course lies with "with all your heart". Is it really possible in our fallen nature to seek God with our full heart? The common saying is that the mind is willing but the flesh is weak. Yet this is not completely true. The flesh is obviously weak, but how can we be completely certain that the mind is willing? 


Even when I think "God reveal yourself to me!", I also know that somewhere deep within the recesses of my mind there is a part of me that desires to have things my own way. Like St Augustine said in his confessions:


As a youth I prayed, "Give me chastity and continence, but not yet."


Thus it is not only in God's grace that we are accepted as children, but also in his grace that we are able to seek him in the first place. The calvinists therefore do have a point I think. 


However, if the answer is simply to place our faith in God, how can we know for certain that our faith is genuine. Or I suppose, how much faith should we have in our own faith?
