What the Bible says about Bad Attitude

Proverbs 17:22

"Heart" and "spirit" could be interchanged here. The Kiel-Delitzsch Commentary on this verse says:

The heart is the centre of individual life, and the condition and the tone of the heart communicates itself to this life, even to its outermost circumference [what is inside comes out]; the spirit is the power of self-consciousness which, according as it is lifted up or broken, also lifts up or breaks them to condition of the body. . . .

If one is in a good attitude, the chances of good health are increased immeasurably. If one is in a bad attitude, the health plummets, almost like a cancer that eats away at one's health. Heart and spirit affect a person's health. This is an effect of what the Bible calls "spirit." Spirit builds up or breaks down. It excites or calms. Spirit communicates beyond its point of origin. The spirit's point of origin may have been outside of a person, but what happens externally affects his spirit and can thus work to deteriorate his health or build it up, depending its effect on him.

Malachi 1:9

He says, "Go ahead—ask for protection. Ask for guidance. I will not give it to you. Your attitude is wrong! Your offering is wrong!"
