(idiom) heart and soul; wholeheartedly

I want to thank my partner in this journey, a man who campaigned from his heart, and spoke for the men and women he grew up with on the streets of Scranton, and rode with on the train home to Delaware, the vice president-elect of the United States, Joe Biden.

If one person's qualities are really good, say this means they have one hundred points, but of those hundred they only give you thirty or forty, or even ten or twenty. Inversely, another person maybe only has seventy or eighty points, but they treat you with their heart and soul, then which person should you choose?

I support you whole-heartedly.

Since then he has put his soul into his work.
