Complaining and criticizing is contrary to the common good. In scripture, we are reminded that we exist for the common good (1 Cor. 12). Yet, those who grumble, complain, criticize, and seek to manipulate do so for their own benefit. These actions display a lack of trust in God. We need to grow our trust, recognizing God as a God of abundance, who provides us what we need, when we need it, and follow his lead into his kingdom.
