Infused righteousness is when God gives us the ability to be good and do good things by putting a special power called grace inside us.
Think of it like having a superpower, like being able to run really fast or jump really high, but instead it's the power to do good things like helping others, being kind, and loving our enemies.
This power doesn't come from anything we did, but it's a gift from God because he loves us. When we believe in God and trust him, he gives us this power and helps us use it to make a positive impact on the world around us.
