Our lifestyles seek comfort. Our society emphasizes comfort. Yet, often it is. Such things can be unquestionably good, but unquestionably uncomfortable. Nothing equals the comfort these gifts provide.
Salvation also contains elements of great discomfort.
Repentance, when understood, is uncomfortable. So is acknowledging personal flaws and weakness. So is confession. So is learning humility, unselfishness, forgiveness, mercifulness, kindness, and compassion. Perhaps our greatest discomfort is experienced by learning to be God's church.
