Protestants for over 500 years have been seeking news, good news, to rejoice, to celebrate, to liberate them from the confessional booth. For when one speaks of sin and forgiveness, mortal sin and its effects, the separation of the soul from God upon deliberate act and will with knowledge of wrong, there is no room for joy, only sorrow for sin.
However, it is of course not correct to replace the hard work, not the good works, of acquiring faith, hope, and love, and grace within the soul, with an advertisement on how we are saved by faith apart from hope, love, and true union with Christ, dwelling within.
For when you are in a state of grace, you will say, "What a wonder, I never knew, Christianity is supernatural," and you will see that all those gifts of the Spirit, the fruits - love, joy, and peace - are real, not just a product of thoughts, but booming, rupturing, from within the soul into the heart and into our very eyes without cognition, but simply by seeking true forgiveness through prayer and even confession when needed.
True assurance is not possible then, one may say? No, assurance is a fruit of this state, a state of grace, when we can wake up look upon the clouds and say, "I have eternal life," with no one able to tell you otherwise.
