No, Mr. Platt.
The central message of Christianity is about the God who caters to Himself - who overflowed with self-worship in the creation and redemption of a people who would passionately pursue their own, individual, personal happiness throughout their entire life, utilizing every aspect of His creation in a way that fulfills all of their deepest rational desires and magnifies the greatness of His self-exaltation.
The fact that this life-long, passionate, ‘self-catering’, pursuit implies that there will be instances of ‘abandoning’ minor, short-term and concrete-bound ‘pleasures’ is just that: an implication – a minor implication which is to be noted and moved beyond.
The only way that such a small implication could be confused for a central end is by the disgrace of a marred and truncated worldview: Truncated, because its myopic vision can only see the immediate phenomena of the transaction (the ‘price’) without relation to the greater and ruling context of that which the price serves (the obtaining of a greater value); Marred, because its tainted vision can only see the negative (‘loss’ or ‘self-abandonment’) without relation to the greater and ruling context of that which inspires, fuels, and triumphs over the negative (ultimate self gain).
To advocate ‘self-abandonment’ apart from the infinitely greater context of self-value and self-gain is to ignore or belittle the greatness of God’s happiness in Himself – from which and to which flow His apparent ‘sacrifice’. Worse, to insist that ‘self-abandonment’ be the center of Christianity, is to insist that ultimate self-obliteration be the central aim of God, and rightfully, also, His people.
