JB Van Hoogen :: BGC Values series. The last installment in our 5-part series on BGC’s core values. We have responded to the simple invitation of Christ, and are called to contend for a "sincere and pure devotion to Christ" as Paul exhorts the Corinthian church. What does this sincerity and purity of devotion mean for our life as Christians and a church? It means a commitment to simplicity.
