Hot saints have such a halo round about them that they reveal—make manifest sins in others. They do this by contrast. “What fellowship can light have with darkness?” (2 Corinthians 6:14). The light of God flashed from a hot saint onto the dark consciences of sinners makes them feel their sin.
A dark soul cannot dwell in the presence of a soul full of light without either repenting or opposing; if it does not submit, it will rebel. It was under the hot blaze of this light that the Jews round about Stephen “were cut to the heart, and gnashed upon him with their teeth” (Acts 7:54 KVJ). When intense spiritual light and darkness are brought in contact, their innate antipathy makes them reveal each other.
Heat cleanses, purges away dross. The burning fire of the Holy Spirit purifies the soul which is filled, permeated with it, hence, hot saints are pure. They purify themselves, as He is pure. They keep themselves “unspotted from the world”
(James 1:27 KJV). They improve the moral atmosphere wherever they go.
Heat burns. Hot saints set on fire the hearts of other saints. They singe the consciences of sinners, melt the hearts of backsliders and warm up those who have left their first love.
Hot saints are mighty. The fishermen of Galilee produced more impression on the world in a few years than all the learning of the Jews had done in centuries, because they were hot in the love and service of God.
Hot people are not only able to work, but to suffer. They can endure hardness, suffer reproach, contend with principalities and powers, fight with wild beasts and hail persecution and death!
To be hot ensures opposition, first from the Pharisees. A formal, ceremonious, respectable religion they do not object to; but a living, burning, enthusiastic Christianity is still Beelzebub to them. To be hot ensures opposition from the world. The world hates hot saints, because they look with contempt on its pleasures, set at naught its maxims, trample on its ambition, ignore its rewards, and live altogether above its level. To be hot also ensures opposition from the devil.
Let me remind you, in conclusion, that to be hot ensures God’s special favor, protection and fellowship, and final victory. “Be faithful unto death, and I will give you a crown of life” (Revelation 2:10 KJV).
