1 Thessalonians 5:6
Therefore let us not sleep, as do others; but let us watch and be sober.
They who in a crazy vessel navigate a sea wherein are shoals and currents innumerable, if they would keep their course, or reach their port in safety, must carefully repair the smallest injuries, and often throw out their line, and take their observations. In the voyage of life, also, he who would not make shipwreck of his faith, while he is habitually watchful and provident, must make it his express business to look into his state and ascertain his progress.
Parallel VersesKJV: Therefore let us not sleep, as do others; but let us watch and be sober.
