Grace is God acting freely, according to His own nature as Love; with no promises or obligations to fulfill; and acting righteously in view of the cross. Grace, therefore is uncaused in the one who who receives. It's cause lies completely in the giver, in God. Grace is absolutely the final authority sovereign not having debts to pay, or fulfilled conditions on our part to wait for, it can act toward whom, and how it pleases. It can, and does, often, place the worst sinner in the highest favor. To be discouraged is unbelief, as to God's purpose and plan of blessing for you. To be proud is the be blind! For we have no standing before God, in ourselves. The lack of God's blessing, therefore, comes from unbelief, not from failure of devotion.
Real devotion to God arises, not from man's will to show it; but from the discovery that blessing has been received from God while we were still unworthy and un-devoted! To declare devotion first, and blessing second, is to reverse God's order, and proclaims Law, not Grace. The Law made man's blessing depend on devotion; Grace gives unconditional, undeserving blessing; our devotion may follow, but does not always do so, in proper measure and response to Grace!
