Temperatures where we live in Colorado can change quickly—sometimes within a few minutes. So my husband, Dan, was curious about the temperature differences in and around our home. As a fan of gadgets, he was excited to unpack his latest “toy”—a thermometer showing temperature readings from four “zones” around our house. Joking that it was a “silly” gadget, I was surprised to find myself frequently checking the temperatures, too. The differences inside and out fascinated me.

Jesus used temperature to describe the “lukewarm” church in Laodicea, one of the richest of the seven cities cited in the book of Revelation. A bustling banking, clothing, and medical hub, the city was hampered by a poor water supply, so it needed an aqueduct to carry water from a hot springs. By the time the water arrived in Laodicea, however, it was neither hot nor cold.

The church was tepid too. Jesus said, “I know your deeds, that you are neither cold nor hot. I wish you were either one or the other! So, because you are lukewarm—neither hot nor cold—I am about to spit you out of my mouth” (Revelation 3:15–16). As Christ explained, “Those whom I love I rebuke and discipline. So be earnest and repent” (v. 19).

Our Savior’s plea remains urgent for us too. Are you spiritually neither hot nor cold? Accept His correction and ask Him to help you live an earnest, fired-up faith.
