Convicting words on the cost of nondiscipleship

Here are some convicting words I just read from a book called: Radical: Taking Back Your Faith from the American Dream by David Platt. We pick up just after he has argued that while the cost of discipleship may seem high (leaving family and friends, forsaking former life, selling all worldly possessions and giving all to the poor, etc.) the cost of nondiscipleship is even higher.

The price of our nondiscipleship is high for those without Christ. It is high also for the poor of this world.

Consider the cost when Christians ignore Jesus' commands to sell their possessions and give to the poor and instead choose to spend their resources on better comforts, larger homes, nicer cars, and more stuff. Consider the cost when these Christians gather in churches and choose to spend millions of dollars on nice buildings to drive up to, cushioned chairs to sit in, and endless programs to enjoy for themselves. Consider the cost for the starving multitudes who sit outside the gate of contemporary Christian affluence.
