I'll give you application! Came across this post by Tim Challies (great blog btw), and found it to be a truly exemplary post. Definitely a great reminder and chock full of applicable truth.
If I may be so bold, though, as to add a quick note to Mr. Challies post. Seeing as this is the Easter season, we as Christians must always remember that we can and should forgive others because Christ has first forgiven us (Ephesians 4:32). As one blogger whose site and name escapes me said, we must always tie our studies and doctrines back to the cross somehow. Hopefully you can see how forgiving others and repenting of our sin are related to Christ's sacrifice.
Happy Substitutionary Atonement Day and Resurrection Day!
