Be On Your Guard: The Threats Are Real
It's Time
January 28, 2018
Rev. Gabe Sylvia
Mark 13’s Olivet Discourse calls believers to be on guard—against false leaders and prophets, the horrors of war, and personal persecution—so they can sustain courageous and enduring gospel witness in the age between Christ’s ascension and his return.
Summary
In Mark 13 Jesus closes his private teaching with the Olivet Discourse, warning that the period between his ascension and second coming will test the church; he gives three exhortations to be on guard so believers can preserve effective gospel witness. External threats—false leaders, false Christs and prophets, and the destabilizing effects of conflict and war—can render our witness ineffective, and when persecution becomes personal believers must endure to the end. Many churches have already been distracted by cultural battles that perish with culture, while the urgency of eternal souls remains; therefore we must prepare, protect the church, remain alert for both dangers and blessings, and commit ourselves to prayer and endurance until Christ returns.
