I don't know what you have read or been taught. but there is much more to most educated people of faith.
First they believe in God's love and second they believe if man was created in God's image that they are capable of great things. That is the reason God trust His children and knows that love will never fail.
If people can believe in someone to do the correct thing then certainly God does the same He being the creator of humans. It is in the darkest hour of mans history that people step up with such amazing belief that problems can be overcame that has save the human race from destruction or evil.
No I don't believe for one minute that people are incapable of doing good and that good will not simply humble the human spirit. I am amazed over and over again of people that have dedicated their lives to serving and solving the worst of humans problems.
From the least to the greatest only make me have respect for a God that could create something so beautiful as humans that are allowed to find new ways to help others.
