So, the whole point of the sacrifice of His Son from the standpoint of God's provision for us: if He would even give the life of His own Son, what else would He not provide for his children??....obviously, there is nothing left....in other words, know that His provision list is infinite...so again, the OT informs us: our God is an awesome God of provision of everything we need, every day....hence why we can put our trust in Him, that He will provide for us....because He's already shown the magnitude of his provision of care time after time.....
Again, something I do not remember being taught in the CoC...instead, God's provision of care came in the written text of the NT only, never directly...it was always an ambiguous, amorphous concept to me....
