Our "only comfort" is in belonging to Christ. His suffering, death, resurrection, and ascension bring us "benefits": His sinlessness covers our sins, His resurrection is the "guarantee" of our resurrection, He "intercedes" for us in heaven and "protects" us. The sacraments, as "visible signs and seals," help us "better understand" the promises of the gospel, pointing to Christ's "only sacrifice" and "guaranteeing" our purification through Christ. In times of weakness, we find comfort in Christ's work and the sacraments.
