'Watchfully' in the Bible

if only you will listen to and obey the voice of the Lord your God, to observe carefully all these commandments which I am commanding you today.

casting all your cares [all your anxieties, all your worries, and all your concerns, once and for all] on Him, for He cares about you [with deepest affection, and watches over you very carefully].

and we receive from Him whatever we ask because we [carefully and consistently] keep His commandments and do the things that are pleasing in His sight [habitually seeking to follow His plan for us].
