I think worries/cares are the most dangerous....these are the ones that I think we sometimes put before God. These are the ones we sometimes think we have no control over or decide to handle on own. Unawaringly, we sometimes fall as prey to them. Seeking riches are pleaseures are more deliberate choices which we open-eyed get ourselves into, just by refusing to die to self. Worries/cares sometimes involve our concern for others more than ourselves, but the danger comes, when we make those things, situations, or people our idols or gods. How to please people is a snare to many believers! We become more concerned about pleasing peole and less concerned about pleasing God, a great danger, example: Aaron and the molten calf in the wilderness!
