He’s known as the military man whose commencement speech about making your bed every day got 100 million views online. But retired Navy Seal Admiral William McRaven shares another lesson just as compelling. During a military operation in the Middle East, McRaven has sadly acknowledged that several members of an innocent family were mistakenly killed. Believing the family was owed a sincere apology, McRaven dared to ask the heartbroken father for forgiveness.

“I’m a soldier,” McRaven told him, “but I also have children. I know how difficult this would be for me if this tragedy happened to my children.” The man’s response? He granted McRaven the generous gift of forgiveness. As the man’s surviving son told him, “We accept your apology, and we will have no more hatred in our hearts for you.”

The apostle Paul wrote of such generous grace: “As God’s chosen people, holy and dearly loved, clothe yourselves with compassion, kindness, humility, gentleness and patience” (Colossians 3:12). He knew that life would test us in various ways, so he instructed believers in the church at Colossae: “Forgive one another if any of you has a grievance against someone. Forgive as the Lord forgave you” (v. 13).

What enables us to have such compassionate, forgiving hearts? God’s generous love. As Paul concluded, “Over all these virtues put on love, which binds them all together in perfect unity” (v. 14).
