Pride is opposed to humility as a polar opposite.
In short, here is the problem. I am proud, not humble. If I try to act humble, I have just added hypocrisy to my sin of pride. <smiles> For humility is unnatural for me. Thus, like many of the things Jesus requires of us that are humanly impossible, "without Him we can do nothing". But with Him... we can.
