About a decade ago, I followed John Piper and his ministry "Desiring God", with great joy.
I listened to sermon after sermon; purchased books for me, my darling husband, sons and sent them as gifts for friends and family.
I shared links to their blog articles, retweeted their tweets, shared their materials over every social media platform I participated in, just to soak up and share what I thought at the time, was entirely, soundly biblical wisdom.
I share all this to show you how much Piper and his ministry "Desiring God" has, in some ways (not all), been led away from sola scriptura (Scripture alone), so that you might be more discerning about following their ministry (writings, sermons, etc.).
I know I can be easily deceived just like Eve, and desire all that feeds my flesh and makes it feel good through emotional and sentimental hogwash.
With that said, it would be unwise for me personally, to continue to follow John Piper or his "Desiring God" ministry as he/they continue to engage and condone unbiblical practices.
I've found the teachings from John Piper and "Desiring God" (after testing it with God's word) requires more discernment than I currently possess.
With this hunger and resolve to have a heart more like Abraham and Isaiah, I wanted to obey God immediately—with joy, and use the gifts He so graciously bestowed upon me, for the purpose in which He gave them: For the encouragement and edification of those within the Body of Christ (Eph -16) without usurping God's authority of male headship within the church, and to go out to all the world preaching the Gospel, discipling young girls and women of all ages.
But in 2006, there was an uproar within the Christian community after John Piper extended an invitation to a young, filthy mouthed, unabashed preacher from Washington state, Mark Driscoll, to be one of the speakers at his Desiring God National Conference. Though Piper was questioned and criticized (and by some, too harshly and unbiblically), he stood by his young protégé and extended two more invitations to speak at their national conference (20), though Driscoll proved to continue to get carried away by strange and unbiblical behavior like having pornographic divinations about other people's lives, and speaking harshly, including name calling to rebuke those within his church.
Unfortunately, Piper's lack of obedience to God's word in 1 Corinthians "Do not be deceived: 'Bad company ruins good morals.'" continued to perpetuate his decline in discernment as he extended an invitation to Rick Warren (2010) and Louie Giglio (2011) to be speakers at his Desiring God National Conferences as well.
Then at Passion 2012, Pastor John Piper condoned and participated in Louie Giglio's practice of a meditative, mystical type exercise that closely mirrors the heretical "Lectio Divina" where Catholic priests believe that God directly speaks extra-biblical messages to those who engage in this mind-emptying practice (click link to listen to Todd Friel's "Wretched" radio program on this topic).
And since there are other Christian teachers/ministries I can learn from (e.g., John Mac Arthur/Grace to You, Alistair Begg/Truth for Life, R. Sproul/Ligonier Ministries) that don't give me tired-head, I've chosen to only follow those who are clearly and faithfully following the Lord (Heb 13:7).
