"The lot is cast into the lap, but its every decision is from the Lord." Prov 16:33
I can interpret that to mean that God is involved in every decision. IF every decision rests entirely with the Lord, explain my tagline. YOU CHOOSE...

It's our decision but God already knows our decision. He made us so we will act just as He predicts we will act. He is not surprise. For example Adam was given the task of naming the animals. Adam could name them anything he wanted and God would not interfer. God knew Adam would "chose" the correct name and what that name would be; simply because God gave Adam his knowledge and fashioned his understanding.
As far as you tagline, I believe I've already address that. Deut 30:19, "Choose life..." is the outward calling of God. Read Deut 31:16,
God commands, but then He must give what He commands. God commands us to have faith in Him. Yet He is the one who gives us our faith. Instead of reaching inside ourselves for something that just isn't there, we should be praying to God to give us the thing that He has commanded.
