It's a pure blessing to accomplish things of eternal value every day.
Everytime kids are bickering I have the opportunity to steer them toward Christ -- helping them see the sinful nature we all have and our need for forgiveness and grace.
When the kids are learning about natural things in science I can help lead them to see God's glory.Or when we are reading the stories of human triumph as well as terror and tyranny I can guide them toward seeing God's threads of grace woven through all of time as he sovereignly lays out the plan he has for his creation.
There are an unquantifiable amount of opportunities for me to learn more patience, more caution, and more prudence.....and even more lessons to learn in being more merciful, longsuffering, and less self-centered.
I'm a forgetful person, so now I have this post to look back at when I need it.
