While acknowledging the value of understanding our culture for evangelism, Myers says it's even more crucial for discipleship because:
....our culture also conveys pervasive and subtle challenges to Christian faithfulness. So it is important for us not simply to be able to rebut the errors of bad thinking, but to identify the ways we believers have unwittingly conformed the shape of our lives to the patterns of practice and affection encouraged by the culture around us, and thus have come to embrace a mentality, a sensibility, an array of deeply held assumptions about God, about Creation, and about human well-being that are contrary to those found in Scripture.
It is tempting for believers to live with a small package of Christian assertions on top of a huge foundation of anti-Christian assumptions. We want to make Christian claims about a few things without doing the hard work of reforming our conscience and our consciousness in ways that fully honor God.
