LUKEWARM PEOPLE attend church fairly regularly. It is what is expected of them, what they believe "good Christians" do, so they go. (Read: Isaiah 29:13)
LUKEWARM PEOPLE give money to charity and to the church... as long as it doesn't impinge on their standard of living. (Read: Luke 21:1-4)
LUKEWARM PEOPLE tend to choose what is popular over what is right when they are in conflict. (Read: Matthew 23:5-7)
LUKEWARM PEOPLE don't really want to be saved from their sins; they want only to be saved from the penalty of their sin. Lukewarm people don't really believe that this new life Jesus offers is better than the old sinful one. (Read: Romans 6:1-2)
LUKEWARM PEOPLE are moved by stories about people who do radical things for Christ, yet they do not act. Lukewarm people call "radical" what Jesus expected of all His followers. (Read: James 4:17)
LUKEWARM PEOPLE rarely share their faith with their neighbors, coworkers, or friends. (Read: Matthew 10:32-33)
LUKEWARM PEOPLE gauge their morality or "goodness" by comparing themselves to the secular world. They feel satisfied that while they aren't as hard-core for Jesus as so-and-so, they are nowhere as horrible as the guy down the street. (Read: Luke 18:11-12)
LUKEWARM PEOPLE say they love Jesus, and He is, indeed, a part of their lives. But only a part. They give Him a section of their time, their money, and their thoughts, but He isn't allowed to control their lives. (Read: Luke 9:57-62)
LUKEWARM PEOPLE love God, but they do not love Him with all their heart, soul, and strength. (Read: Matthew 22:37-38)
LUKEWARM PEOPLE love others but do not seek to love others as much as they love themselves. (Read: Luke 14:12-14)
LUKEWARM PEOPLE will serve God and others, but there are limits to how far they will go or how much time, money, and energy they are willing to give. (Read: Luke 18:21-25)
LUKEWARM PEOPLE think about life on earth much more often than eternity in heaven. Regarding this, C.S. Lewis writes, "If you read history you will find that the Christians who did most for the present world were precisely those who thought most of the next. It is since Christians have largely ceased to think of the other world that they have become so ineffective in this." (Read: Colossians 3:2)
LUKEWARM PEOPLE are thankful for their luxuries and comforts, and rarely consider trying to give as much as possible to the poor. (Read: Matthew 25:34, 40)
LUKEWARM PEOPLE do whatever is necessary to keep themselves from feeling too guilty. They want to do the bare minimum, to be "good enough" without it requiring too much of them. (Read: Matthew 13:44-46)
LUKEWARM PEOPLE are continually concerned with playing it safe. This focus on safe living keeps them from sacrificing and risking for God. (Read: 1 Timothy 6:17-18)
LUKEWARM PEOPLE feel secure because they attend church, made a profession of faith at age twelve, were baptized, come from a Christian family, vote Republican, or live in America. (Read: Matthew 7:21)
LUKEWARM PEOPLE do not live by faith; their lives are structured so they never have to. The truth is, their lives wouldn't look much different if they suddenly stopped believing in God. (Read: Luke 12:16-21, Hebrews 11)
LUKEWARM PEOPLE probably drink and swear less than average, but besides that, they really aren't very different from your typical unbeliever. They equate partially sanitized lives with holiness, but they couldn't be more wrong. (Read: Matthew 23:25-28)
As 2 Corinthians 13:5 says, it is a call to "examine yourselves, to see whather you are in the faith; test yourselves."
We are all messed-up human beings, and no one is totally immune to the behaviors described in the previous examples. However, there is a difference between a life that is characterized by these sorts of mentalities and habits and a life that is in the process of being radically transformed.
Jesus didn't say that if you wanted to follow Him you could do it in a lukewarm manner. He said, "Take up your cross and follow me."
Jesus asks for everything. But we try to give Him less.
He is saying that lukewarm, halfhearted following is useless (in Luke 14:34-35), that it sickens our souls. Lukewarm and uncommitted faith is completely useless.
