There are few more important themes in Scripture than that of grace. One of the hallmarks of Christ is that He was full of "grace and truth" (John 1:17). The gospel is all about the grace of God applied to our lives, His unmerited favor given freely to us not only in salvation but on a daily basis!
As one reads the gospels, one sees Christ interacting with graciousness with all, with the exception of the Pharisees who were hypocrites. There was always truth in His conversations but it was a gracious truth.
Organizational leaders set an example and monitor the culture of the organization or team that they lead. In the Christian world, one of the hallmarks of our ethos should be a graciousness in our interactions with one another.
There are many attitudes that do not exude grace: gossip, cynicism, mistrust, assuming the worst rather than the best, anger, and impatience. These are often encountered but they do not reflect the character and attitudes of grace. In fact, they are the opposite of grace: ungracious judgement of others.
This does not mean that we cannot address questions, issues or press into dialogue on difficult subjects. Just the opposite should be true and Jesus certainly did not dodge the difficult conversations or issues. What it does mean is that as we interact with one another, the grace that Jesus gave to us ought to be evident in our interactions with one another. His grace to us ought to be our grace to one another. To not show grace to one another is to deny God's grace to us.
Grace and truth is a powerful combination that creates a unique and God honoring ethos in any organization. Leaders model it and call others to it.
