Why should we justify God according to the sermon?

In the sermon, the concept of justifying God involves recognizing and agreeing with the truths that He reveals through Scripture about mankind. To justify God means to declare that all He says and does is right. This agreement is rooted in the understanding that we are sinners in need of grace; acknowledging our unworthiness and need for redemption through Christ is fundamental. The response of the people who justified God by being baptized by John illustrates the proper attitude toward our creator — one of humility, conviction, and a desire for His mercy. In contrast, the Pharisees who rejected this call exemplify self-righteousness and a refusal to align themselves with God's assessment of their condition.
