I believe in grace, not legalism. Today I preached on the sermon on the mount in Luke. I came face to face with the problem that Jesus preached a lot of commands, and ended the sermon saying that those who kept the commands would be preserved and those who didn't would be destroyed (the house on the sand).
How come Jesus didn't say "I love you and nothing you can do will make me love you more or love you less"? Instead he gave us a set of commands that are even harder to keep than those of Moses, and said things like "Whoever has my commandments and keeps them, he it is who loves me. And he who loves me will be loved by my Father, and I will love him and manifest myself to him." (John 14:21). I don't believe that we are loved on the basis of our performance, but this is what it sounds like Jesus is saying.
So I decided to tackle the subject head-on and preach on Luke 6. I don't believe the answer is some sort of "balance between law and grace" that requires us to water down grace and weaken law. My solution is far more radical that that: In a nutshell, what Jesus is preaching is not law but faith, and faith is the proper response to grace. I have uploaded the sermon here: "Why Jesus' commands are not legalism" together with the notes. I would be interested in any responses.
