Why would the salvation wrought by Christ need to be sugar-coated? In itself, of itself, it already promises knowing our Creator personally, living forever without disease, decay or death, and being free from doing stupid things we will rue but do regardless (among other things). Could there be a sweeter deal? Salvation is an absolute dream come true, but being a disciple of Christ comes at a cost even though it is truly free.
Salvation entails acknowledging that we don't run the show and us bowing to the leadership of Jesus. In this day where willfulness is celebrated and self is elevated, the temptation is to assume that most of the people we're trying to coax into the Kingdom of God won't buy into such a deal. So, repentance is soft-pedaled, sin and judgment is back-pedaled, and continuing on in life with Jesus merely added on is floor-pedaled. Can such a vitamin supplement approach to the gospel actually cleanse the conscience here and now or ready the soul for a welcome in the age to come?
It's not those who call Jesus, "Lord" who are saved but those who actually do as he says.
Buying into the gospel means selling everything else we had before the gospel came into our lives (at minimum, in attitude). Families may ostracize or desert us. Riches may have to be abandoned. Sexual pleasures will not be guaranteed to us. Just because we had a dream doesn't mean that God will buy into it or help us to achieve it. It's the price of Jesus being Lord.
A gospel that doesn't stop us in our tracks is not going to get us on the right track.
I like toast with breakfast. As a kid, I particularly like cinnamon toast. When mom made it, most of the sugary coating was shaken off back into the bowl. When I got my hands on it, I usually found a way to load those tasty slabs of cinnamon goodness with more sugary sweetness. If mom ever saw what I was doing she would never have stood for it, but then she cared about my health and wanted me to enjoy having teeth for the rest of my life.
Making adjustments to the gospel makes what is adjusted no gospel at all. If we truly care for those we try to win with the gospel and want them to be whole throughout all eternity, we need to stick to the truth that sets sinners free. Coming to grips with who and what Jesus is and following him exclusively is food and drink indeed. If we want to feed the folk we preach to something that can nourish them eternally, we need to stop sugar-coating the Bread of Life.
