Sandy Millar has this take on Peace and Joy. He says,
"Jesus didn't die to make us peaceful; he died to reconcile us to God. Once we are reconciled to God we are at peace. Jesus didn't die to make us feel good or happy. He died that we might be forgiven. Once we are forgiven we begin to feel good and at peace. They are by-products of the relationship."
May you and I enjoy these glorious by-products of what Christ has already done for us.
