John 15:5 I am the vine, ye are the branches: He that abideth in me, and I in him, the same bringeth forth much fruit: for without me ye can do nothing.
Isn't that what Christ is saying here? You have no ability in yourself to choose Life. Without Christ you are dead in the water.
If by total depravity you mean total inability to be sinless before God by your own choice and will then yes I believe in total depravity.
So if God placed before us blessings and curses in Deut 30, and tell us we have a choice, did he meant it? Take note that, under the Mosaic covenant then, health and finances are under the blessings, while sickness and poverty are under the curse.
