The obvious answer is, ‘No!’ The good news of Jesus Christ suffering and dying in the place of sinners like us is the beating heart of all the true good we know, for in the Lord Christ life eternal is both received and sustained.
In that sense it is and always remains life and health and peace for us, and converted people go on needing the gospel just as much as we did before, to anchor us and to feed us and to strengthen us and to lift us up, that we may speak and live to the praise of the glory of God’s grace.
